gm charger.. a few questions
Tuesday, March 21, 2006 4:45 PM
first off.. i've been looking around for the best price, and most of the posts i have found recommend paceperformance, and thats all good, 2400$ isnt really that much...

...but on gmpartsdirect.com.. they are selling it for 2044$... but as soon as you add it to the card, they tack on like $430 to ship it to you. seems a little.... out of control. i know the dealer price is 2044$, because my dad works at a plant in ohio. i thought he could get dealer price, but it seems they do not offer discounts on 'performance parts'. kind of a rip off...

now, i've been kinda out of the loop for a bit because i've been tinkering with my talon, and just using the sunfire as a daily driver. but i've come to the conclusion that i need boost whenever i drive, and i don't feel like going through the hassle of turboing the sunfire, as it is alot more than i really have time for... but i have a few questions on people set-ups.

1) when running bigger pullies are people upgrading their injectors? i'm not seeing any mention of injectors when looking through peoples mod lists, i know when i first started checkin out the supercharger people were suggesting fpr's and injectors when running more boost. are you remedying this by spraying alcohol?

2) when gettin the reflash.. does every dealership do it? or just the performance parts dealers? and i'm assuming the average cost of the reflash is like $200 right?

i'd like to run really low 14's and maybe some 13's with an auto without nitrous.. i was going to run alcohol injection anyways because of the heatsoak issues, and run a 4-1 header and full 2.5" exhaust sometime after i get the supercharger. i don't feel like coughing up 400$ for a 60mm TB, so until i can manage to get to a junk yard and find a spare one to bore out.. that will be stock also. any other ideas? i'm basically inquiring more about what the 13second gm supercharged vehicles have done.

1 most havent up'd njector size , using alky for the smaller and to help keep it cool

i needed to i was running low to mid 13's on my wide band

2 reflash = 1 hour + dealer labor rate

any dealer can do it , but most are hesitant to do it


im at 14:38 with mine , and 2 1/4" full exhaust 59mm tb , header , i still got more room to play , but gotta get some drag radials

i also saw that you had venom fuel rail, and different fpr..

pretty sure the fuel rail makes 0 difference, but anything going on with your fpr? also what size pulley are you running?

the venom rail , is just for use for my fuel pressure gauge , and dont let anyone tell you you will see power from it


ive got the accel adj fpr , and ive got the base fuel pressure down to 30 psi , and im runnng the 36lb injectors from the 2.0 eco s/c


my pulley size ive never measured , but i will see 5-7 psi with no problems , and in good cold weather , ive seen 8-9 psi at redline


but 7 is the usual max i see

i keep forgettin that you have the two piece prototype. so if i would like to run roughly 9-10psi, i should probably upgrade injectors and get a fpr, or will spraying alkie be a worthy substitute?
