Another stage 2 Whipple dyno...

Made 687/525.

Stage 2 Whipple, 3.625 pulley bone stock motor minus opg, ts, and ATI damper. Exhaust is all stock too minus resonator delete H pipe.
93 octane+octanium.

nice numbers. How is the AFR? What about timing degrees on octanium?

Not much to complain about with that kind of bolt on power!

Nice numbers especially with converters,easily another 30+ hp their.

what rpm did they let off? Curious to see the actual graph and where the peaks were.

AFR was definitely on the safe side. Timing was 23 degrees between 3-4k I believe and the rest of the pull it averaged 19 or 20. Give me some time and I'll pull up my datalog and get some definitive numbers for you.

I actually got to run the car on the dyno (for 2 pulls, I let him do the last one so I could get the video on my phone), was pretty sweet. But we took her up the limiter (7800) in 5th gear.

Graph is up now too

Also if you want to see any one pull by them selves let me know. I have the actual winpep program and the dyno files themselves so I am able to change the graphs at will.

nice thanks! I'm actually going to swap OPG, CS, thermo and few other stuff this weekend in order for re-tune next week with race fuel hopefully will reach the 800 mark.....

Very nice! Add a full exhaust and you're looking at an extra 30-40 hp

I just got my car up on stands and started ripping stuff off to do my Whipple install. Super excited!

sexy runs! Thanks for the dyno!

WTF 3.625 and 13 PSI?

i have this on order i thought 3.625 was supposed to be 12 psi peak with 11 psi.

Nice stuff, especially with everything else stock. Not bad at all.

Relax buddy his boost is a little higher because he has cats,actually if he removed his cats he would make less boost but most likley make more power.Exhaust causes backpressure causing higher boost.

13 psi is high, and likely not an accurate reading for the 3.625", bigjohns is correct. Whipple has tested these pulley combinations with stock motor, exhaust and cats and the 3.75" makes 10-11 psi and the 3.625" makes 1 psi more 11-12 psi. So in reality we are only talking about 1 psi margin of error. No two Dyno's will produce the same results, and likely neither will the boost.

Edit: if you look at the graph the boost spikes above and below the 11psi, so one should not pick the low spike and say is ran 9psi noe should they pick the high spike and say it ran 13psi but rather the middle which to me seems more like 11psi. In fact the graph shows a peak spike of 14psi at the end, surely we wouldn't say it makes 14psi on a 3.625" pulley:doh:

I really think it's the extra RPM here after carefully looking at it, not worried i won't be spinning mine near that high.
