Finally, the time is here im getting tuned this weekend by a local tuner , since im new at all this tuning i was wondering if u guys can help and tell me how much power should i be making with the stock ecu fallowing mods?

Engine
----------------------------
custom gt3582r
double pumper
1000cc injectors/perrin fuel rail
cosworth 272/272
spring & rtetainers
custom licp & uicp
exedy twin disc
tial bov
my goal is 500-520 whp on race gas what do you guys think?

 

it depends on how far u want to push the motor with the tune.

i put down 526 with a 35r @ 30psi. i run 100 octane all the time though, u can do it on 93 just with a more aggressive tune.

i dont know what gas youre using or how good the tuner is, but it should be atleast 450+

 

just out of curiosity who is tuning your car ? there are plenty of reputable tuners in FLAWWWWDAAAA.lol.

 

What dyno? Who's tuning?

 

i think youll make 500 on race gas in the 30psi range
i have alot of the mods you do including the same cams on a red i made 430 on pump at 26psi so i think its very possible. what tuner and dyno machine by the way

 

Jestr is coming down the first week of Jan and there will be a dyno day at Awdmotorsports in coral springs. It has always been a great turnout when he comes down. I Had a gt35r with the same mods u had without cams and made 454 on 25 psi on pump gas. Put some q16 and on 29 psi i made 534. Hes a great tuner. Let me kno if u want to get tuned by him ill put u on the list.

 

don;t mean to jack this post but i was just wondering , the guys that have been runing 28psi + have ur engines busted? i heard 4g63 can handle upto 500whp depending on the tune, but its hard to belive.
thanks,

 

im on stock block on a safe tune on my red.

john is coming im willing to say if he tunes you your going to make it. not putting down any other tuner of course, i trust my tuner and shop in every aspect of my car and build and tune

 

if the fp red an equivlent of the 20g?

 

i say 450-460 low boost and 520+ with 29-30psi

 

nope, stock block with 40k on it. i just change my plugs every 800 miles as cheap insurance. but 800 miles take me about 4 months lol.

its a weekend warrior to chew on all the ls1's and ls7's

 

NICELY DONE!.....lol

 

Iam learning at the moment and going to do the obvious mods at first then most likely drop a big turbo in there but not sure which one to go with yet, been readin many threads on the red, green, white and 35r's.... so will see how it goes.

 

only two turbo upgrades i would suggest someone from my perspective would be either a red, or 35r

 

i don't think you'll have a problem reaching your goal on mike's dyno
