I was reading a post before, and a guy claims to have ran like a 13.9 with 7lbs of boost on his stock internals HAhn stage 2. Has anyone else ran times this good or close to it at least? If so, what are your best times with that kind of stock internal set up?

14.50@98.38 on 6.5psi in 93 degree heat....MPH is good enough for low 14's...but thats on a star kit with a much bigger turbo than HRCs and cams and other mods...i never came across a HRC turboed stge 2 car that i couldnt demolish...

when i was stage 2 hrc, smic. i ran a 14.5 with lots of leaks, and first time at a track.

with my mixed setup the best ive ran is 15.6 after slowing at the end to try not beat my time..lol and being up here in CO with the shitty altitude/thin air that doesnt help, but all times before that i ran 17.0 then 16.2 than 16.5 then hit the 15.6. and i'm running really rich on stock internals.. have to do more adj to see what its really capable of hitting. whats your fuel settings like?

Eh? Why would you want to slow down to not beat your time?

Also, with numbers like that... are you AT? I can prolly put down a low 16 near-stock.

i slowed down cause i was bracket racing..cant let the other person beat u and u cant beat your time you listed..and im MT. I know i should be running faster and cant figure out why im still slow.. any suggestions.

Tuning? You got a good fuel system and something to tune it w/ (S-AFC,etc)? W/ no tuning and a clutch going out I still managed 15.3 at 6psi and shifting around 5500-6000rpm. You should be in mid 14's at 6-7psi.

Ooooh yeah, I didn't think about that :D

I'm thinking either a boost leak or just horrible tuning. If you are running too rich that will definitely kill performance (along with your O2 sensor)

What's your fuel system look like?

Well i also heard back from hahn about this and they said bout the same.. gave me some fuel ratios i should be at. i have a feeling im pushing way to much fuel i have 440 injectors and a sfmu but no controller i had/have the blitz one but hate it, it keeps switching from 4 to 6 cyl for no reason. i'm gonna adj the fuel ratio and see if that helps.

ps..how much u guys pushin with adiquit fuel? i'm lookin to push max 9lbs psi.. u think thats okay?

Um, I didn't think our stock ECU could handle the 440s...

I'm not 100% on this one but I think that would be your problem: untuned giant injectors.

Someone help me out on this one...

"SIG" In the desert heat of Arizona at 10psi.

our ECU's can handle 440's, it's after 450cc's that the ECU goes whack and you need to switch to stand alone. anyway, i ran a 15.6XX w/ a 2.4 60ft. on stage 1 with the cartech & the stock RS exhaust.

I ran a 15.6@93mph on 6 psi, that run i launched too high and I spun all the way through 1st gear. I only did one run untill they found a leak, which ended up being my valvecover gasket.


I had it set really rich too, with terrible tuning. Plus my engine has 146k and low compression in my #3 cylinder (like 150) as well as a leaky turbine seal.
