Twin Charged sunfire gets 1/4miles times
Saturday, September 20, 2008 4:46 PM
Well I have had it tuned for about a month now, and decided to get out to the track last night since they are tearing it down in a few weeks (it’s a @!#$y track ahah)
It dynoed at 305whp and 315lbs.tq @15psi running 91 octane gas.
So I got to the track last night and it took me 1hr 30min waiting in line just to get my first run, which ends up just being an arm drop start since the tree/clock was screwed up and I got a pretty good start not too much spinning. So I got back in line and an hour later I finally got my 2nd run in, this time the clock was working and I ran a 13.50 @109mph but I had the rpms a bit higher on launching this time and ended up spinning threw 1st and 2nd gear but over all I am happy as that was only my 2nd pass in the last 4years. And after that I didn't feel like waiting in line and just went home
Going to try and get out next Friday and the one after that because it’s going to be the last time we will have a race track in this city , and I want to try for 12's. I was talking to some of the guys at the track and they said with the trap speeds it has potential for mid to high 12’s. Just have to get my launches a bit better.
oh and tire pressure was at 30psi with Goodyear Eagle F1's so I am going to try and go down to 25psi and see if it helps any. Also I am running just a stock differential as my Quaife one is screwed up and off getting work down to it which is also part of my traction problems

Any way here is the time slip. My girl friend tried to get videos but the camera would only tape for like 30sec and shut off… I can upload them if someone wants; there are 2 of my launching and then one of me just going down the track


Track Elevation: 3380 feet, and it was about 18-20 degrees out side

eagle F1's suck my @!#$in balls

decent times though. I'd like to see it run closer to sea level. and is that a typo? last night was 18 degrees outside??? I have a hard time believing that.

At sea level you'd be about 13.0 @ 112.9 MPH. Those 60' times are killing you.

nope, i dont believe it. you ran the other time on the slip, 16.3.

awesome man, drag radials and your in the 12's no problem.

I love the F1's, they hook awesome on the Trans Am thats running 400whp way better then my Kumhos I previously had...ahah and yea i forgot to put 18 C out side... I am in Calgary (western canada)

Yea I was just spinning threw 1st and 2nd. Also they do not spray VHT at all for Friday night drag races, they use to last year but this year beacuse the place is being torn down in 2 weeks, they are doing the bare min. for racing which didnt help for traction

ahaha that guy who ran the 16 was SOOO COCKY!! he was in a new GTi with some stage 3 upgrade and was talking crap, so i walked up to him and just asked "you want to race then?" and after the race his dad came up to me and was very nice and wanted to check out the car and such and then when he left said his son was pretty pissed ahaha
As for drag radials, it might get them but probably not... i like to see what the car can do exactly how its driven on the street, meaning no taking out seats, spare tire etc... and actually for my races last night i had spare tire and all that junk plus a cooler fill with... pop..... and other random stuff and a full tank of gas (filled up right before i went to the track)

thanks. If you can I would say do it but there are some disadvantages. the guy tuning my car had to tune in almost a built in traction control system because It was building power so fast I was spinning all threw 1st, 2nd, 3rd and 80% of 4th was still smoke... It still does spin lots but not quite as bad, where as he said he tuned a cavalier a couple weeks before to 315whp and it would spin lots but not until the turbo spooled which he said did take a second or two vs. my set up it would be instant tire smoke. So if you can hold the power to the ground this set up makes for a fun car When it keeps up with a C5 z06 off the line and from a roll at any speed I would say thats big low end power and huge top end (considering Z06's are known for their crazy pull up top) Thats also why my 60' times are so slow, it is hard to keep the tires from going up in smoke. I was only launching at about 2000-2200rpm

Im sorry, but I gotta say this. 305 whp at 15psi? A straight turbo kit could easily get better than that. The m45 is killing your setup, it is being way too overspun.
It is unique though, so you got that on your side.
Good luck getting into the 12s.

thats 305whp on a mustang dyno with 91 octane gas. compair that to a dyno on a dyno jet and it would be closer to 330whp than factor in how close the tuner wants to go to the edge with the tune and there is way to many variables to be compairing one set up to another. I made 250whp @7psi on a bone stock engine before this show me a turbo set up that makes more than that on a bone stock engine.
I went with a safe tune on this because the car is for sale and I dont want some kid coming back 2 weeks after he buys it saying the engine is blown.
And how is the supercharger being over spun? it has a 2.8" pulley on it... last time i checked the stock pulley spinns the supercharger well within its limits. but thanks.
And good luck getting in the 12's? my trap speeds were almost 110mph... you obviously dont have a clue what your talking about and are just spouting out random info. last time I checked, 110mph is enough for a 12's pass given a good launch and shift points. And when im keeping nose to nose with my girl friends dads 400whp C5 Z05 I would say 12's is doable considering the times they can do bone stock with 350whp.

Got to love the Jbody site ahah glad I have moved on to my GTO and to a new comunity that it brings with it full of adults, where kids dont run their mouth on stuff they have no clue about. guess there is a reason I never come on here any more.

Nice times. That said, it took you 2 power adders to get there. Something I've never realy been impressed with on any car thats still in the 13s, hell even the 12s. Just my opinion I guess.

Of course this power can be done with a turbo only, never once said it couldn’t. There are dozens of ways one could reach this power, Nitrous, crazy all engine, turbo, supercharger ahah hell I am sure someone could do it with a damn leaf blower.
Well if he knows so much about cars he sure doesn't show it. Someone who knows about cars would know there is so many variables to a dyno number that you cannot accurately compare one set up to another unless they were both dynoed on the same dyno and tuned by the same tuner. Lastly you would think if he knew about cars he would understand what a strap speed is and that a trap speed of 109.93mph would show the capability of the car and what it can do. That trap speed with an absolute perfect launch, shift points, track conditions, weather conditions is a low 12's pass. Sure I am no pro drag racer and things like track conditions and weather is out of my hands, but high 12's are defiantly not out of the question ask anyone who actually knows what they are talking about.

Any who I normally would not have even bothered to come back to this site but I know there are a few people who were interested in this. But it’s nice to see Jbody.org hasn’t changed and is still full of the followers and people who down play any thing that is outside the norm.

No, those are not the only people here. I understand that lag was part of your build also, not just throwing 2 power adders on to get big numbers, like some of these putz's seem to think.... I seriously was excited to see your post, gimme pics, vids, and any other info! Some of us give a @!#$ lol.

thats true.. there are a few good people on this site but very few.
Any who they are not great videos at all as i said the camera would just stop filming for no reason but I will try to get better ones next friday.

There are quite a few tools on this site but if you're definition of a few good people are the ones who agree with you then you probably shouldn't be posting on the internet.

Lets look at this logically, it took you two power adders, more money, a harder engine to work on and probably more difficult to tune. You said you didn't want lag and a supercharger would have given you exactly that. Most with two power adders are using them for a good reason and usually run single digit 1/4 mile times. If you went to an actual event you'd be thrown in the outlaw class with those cars and get raped.

If you did it to be different and just wanted to try something out of the ordinary that's fine but don't play it off as if it's a better setup when it's obviously not. It's an impressive time for any J-body but for what you have into it I'm also unimpressed. Didn't you have a line in your signature before about "500 whp in the spring of 07" and kept changing the date?

Wrong person, so you might want to relax a bit about that
I think a few of you may be missing the whole point of customizing cars- its actually not to impress some random person on the internet. Although i am very thankful thet people who have accomplished something out of the ordinary are willing to share their experiences and passion for building cars- something that seems to be dissapearing with all the cookie cutter cars out there nowadays.
Everyone seems to be going off about the peak power numbers- completely ignoring the fact that the rest of the graph almost certainly wouldnt look (or feel) like a turbo only car. More difficult to work on or build? Is that seriously even an arguement? I dont understand why people insist on taking the easy way out all the time, does noone enjoy a challenge or thinking outside the box anymore? If you are after easy and cheap sticking to stock or simple boltons is the way to go- but apparently he isnt satisfied with just ordering everything out of a catalog.
Its getting a little rediculous when everyone has nothing but good stuff to say about boltons but bashes anything out of the ordinary.

Well thats probably one of the longer posts i have made but this really bothers me everytime i see it

Hell I went 108.92 with a measly 10 PSI from a turbo. Honeslty after one night of playing with a twin charged setup and seeing what it can do (if set up so that both systems are independent form each other) I wouldnt bother with trying to build one. I only did it because i was swapping from S/C to T/C and wanted to try it out . Your numbers are unimpressive as far as im concerned. I know of a stock 2.4 (had a cam swap) that went a 13.2 ( I may be off by a tenth or two) with a smaller turbo and no S/C, I recommend you learn how to drive that thing.



WTF is a Z05???


Im going to have to side with teh guy that has done numerous v-6 swaps and is building a turbo 3800 on this one.

I thought it was him but wasn't sure thus the ? mark, no need to "relax". Many on this site have custom setups that are far from ordering anything out of a catalog, actually a few people in this post have done something custom. On a show car that wants extra points or attention I can see the point. For a driver running these kinds of times it doesn't make sense, even if he hits the 12s. That's not why I made my post, originally I was going to stay out of this because I would have made a similar comment to Darren's. But that's the internet if you can't take criticism with compliments, shouldn't bother participating.

If you're happy with your setup than that's all that matters. Just don't expect everyone else to feel the same way.

It would be a typo for Z06. I am going to rack my memory here and say, based on what has been in his driveway(I believe his dad owned), he has a bit of Vette experience in his family. I also don't think people read the part(or half the time do anything but flip through threads like they're a @!#$ picture book), where he said he doesn't want to change tires at the track, remove weight, play with gas levels, or go out of his way to make his street car run better times. I think if he just learns the car at the track a bit more, and pulls some slightly better times, he will be satisfied from what I am READING in this thread. I like the twin charged idea, I think it is fairly unique and out of the normal lip kit and black headlights that everyone and their mother gets. Maybe he should just throw some black/polished 18s on it, get a lip kit, throw some out of the box turbo kit on it, all just so this whole forum will accept it as being "omg so sweet!" Seriously. That was my style when I had my cav, modded but stock looking... but I gotta admit an entire forum of people who don't accept anything more gets boring and annoying. Grow up, accept that he doesn't just bolt on what he can find in an RK or GM catalog, and get the @!#$ over yourself if you think everyone gives a damn if your laggy as hell turbo car can run less PSI and better MPH. He isn't building it to race, he built it to enjoy, and raced it to see what it did IN IT'S STREET DRIVEN TRIM.

Way to go for being the first yadda yadda twin charged J to run a 13, good luck with the 12s so that you can come back and have your junk fondled by the fanboys you're looking for.

Beyond that, it is a cool set up, but it seems to be an exercise in excess... if it makes you happy then cool. But to say "and they said this setup wouldnt be worth it man were they ever wrong" Is definitely going to catch hell when the car wasn't fast.

and seeing the bickering from both sides makes me have less respect for both sides. Josh you could have easily side stepped it, but instead you stepped right in it and brought disrespect. Darren definitely does good, smart work, butI think his criticism wias a bit blunt and without the smilies an internet posts needs so people don't get butt hurt. So. on the same lines I think the 3800 is an old technology outdated boat anchor of an engine. But that doesn't give me the right to trash his work for that reason only, and I bet he'd get defensive if I ran in his thread an called his 3800 swap a weak waste of time. So a little more constructiveness and smilies would have saved this thread I think.

Even if both of you are working on less than optimum platforms.

I'm going to have to agree 100%.

Also, one thing i've never liked in this twin charged set up in the turbo. You should have at least used a straight T4 turbo with a huge turbine, that small T3 turbine helps spool but kills power. With the power level you're at you could have used a smaller ball bearing turbo like one of the GT28R's by it self and made more power at low rpm's and top end.

I produced a higher trap speed than you with exactly half the boost pressure with a turbo only, keep telling yourself that people that don't agree with your set up are just jealous followers....
