Before anyone says anything I have searched and all I fould was the sticky about chassis dynos. My question is where can I find dyno charts for FI systems? I'm really only interested in the Vortech SC and Greddy TT. I found one for the Vortech on their site, but no such luck on the Greddy. It will be a while before I go FI, but I'm the sort of person that likes to plan ahead, plus I figured this might be a helpful thread for others deciding. Thanks.

 

heres my greddy kit on stock engine dyno graph from a long time ago. Mods are greddy TT with IC, CJM S1 fuel system, 1000cc injectors, borla dual exhaust, 2.25" test pipes, and a FCON. was great and reliable and never had a problem once. Boost is 9 psi. I would have turned it up a few psi if I knew then what I know now.


my greddy kit on built engine with stock plenum and 2.25" borla exhaust from last year


Those graphs are SAE correction. Using the STD correction that some guys are using lately, that second graph is 586rwhp and 548torque.

new graphs coming this weekend i hope. we will see how that old tune holds up on the new engine BTW, I blew my headgaskets last year, for my "new engine" i swapped to an un-sleeved block and changed the pistons to CP, HKS headgaskets, and BuiltZmotors did a half inch headstud conversion for me.

 

First of all never believe any power figures you see on a manufacturer's site. There are plenty of dyno sheets on this forum, probably one dyno thread per page. You will find a lot of them just by browsing through the threads.

Phunk - pardon my ignorance, but what's the general difference in SAE and STD correction? I've seen it on a few dyno sheets lately too, and wonder how it compares (I notice yours was a little higher STD). Thanks

 

I would have to look up precisely how it calculates different, but STD always reads higher. Its not much, but once your in the 500s+ you can typically see 10-20 more from it. There are some other online communities that only want to see STD graphs :shrug:

 

Greddy TT Kit w/ Stock Exhaust

Red Line - 4.5 PSI - 345 whp / 320 ft lbs tq
Blue Line - 7.9 PSI - 401 whp / 420 ft lbs tq

 

Doug what was the correction on that dyno? Curious, nice TQ curve

 

i don't know

 

Turbonetics ST at 9PSI dyno. On the reflash too BTW. (taurran's dyno)

 

I think he only wanted Vortech and Greddy

 

That's cool. I think a thread with as many kits as possible would be helpful to anyone looking into FI.

 

Yeah, this is useful. Good #'s.

 

Vortech. 3.33 pulley, car completely stock.

 

seems like a good thread. Everyone shoul dpost there dyno and FI kit. This would consolidate the numbers shorten the search. Be kind of hard to ask a question about what a turbo kit does and how much power it gets if dyno charts are posted.

What you think? We have two already. All you dyno Kings go ahead post.
