Went to dyno today (Video)

[Civib2]

well i went to the dyno today and laid down 193whp and 173torque at 7psi a little dissapointed does anybody know what that is at the crank? I ran a little lean from about 4500-5500 but then the computer retarded timing and power went down to about 180whp kind of sucks. Im going to the track on friday i hope to break 15sec.

Seems pretty average to me for 420a-T W/ Stock Internals

what is your turbo setup? Give a list of parts. I am boosting my N/A with the same PSI.

 

[siueclipse]

that whp is about normal

 

[GSGoinFast]

im not sure why your dissapointed with that, my goal is 200whp, and thats pretty damn close

 

[TeamFusion]

What are you trying to reach??

 

[pr0]

Dude I got 123.1 whp at 5 PSI with my auto. Your 170 is pretty good.

 

[Civib2]

yeah 200 was my goal too, so im not sure what to do, the guy at the dyno said i should get an SAFC and he will tune it to hit 200whp. Its a star stage 2 turbo kit

 

[Civib2]

i could probably push it to 8psi but then its more risky and i dont have th emoney for a rebuild

 

[truECLIPSE]

8 psi should be safe I remember reading about some guy on these boards or 2gnt who boosted at 10 psi for a couple months or so and said it ran completley fine and didn't break anything. I am not telling you to run 10 psi I am just saying that your 8 should be fine. Hahn and Star both agree 8 psi is the safe limit on a stock motor

 

[Civib2]

Well i think im going to keep it at 7 if i ever need to i can boost to 8 if im worried about someone beating me but oh well. I might bump it up to 8 on fri when i go to the track.

 

[TeamFusion]

I did 8 with a Hahn stage 2 and my head gasket went. Learned my lesson, build your motor, nothing is "safe," when boosting.

thats not the motors fault, thats chryslers paper head gaskets fault

 

[Civib2]

yeah the headgaskets do suck but i already replaced mine last summer with an MLS one but to no surprise i think it started leaking again a couple weeks after i replaced it

 

[Ajax]

I was able to get 198 with only 4psi of boost but I was running extremely lean so lean that my forged internals melted, but #@$$ happens taking the shop to court and hoping I can get some money back.

 

[BigRand]

So quick recap, hahn says that with 9-10psi of boost you can have 250-275 at the crank. Which is ???whp?

So running the star stage 2 kit with 8psi and tuned with an SAFC is 250hp to the crank possible?

Anyways 200whp is my goal too, but I really thought I'd be pushing around 180whp with just 5psi Oh well.
