Very nice numbers! Ken has tuned my Cobra several times aswell, he rocks!

my tuner is giving me shit about going 3.25 + 4lb. lower on pump....what u guys think?

IMHO that would be pushing it on pump gas. Personally myself I would never try to run that much boost on pump gas.

keep your stock lower and go with a 2.75 and a good aux idler setup.

Nice numbers but I would be concerned with the A/F on that graph. It looks to me to be around 12:1 and drifts north of that to around 13:1 at the end of the pull.

sleeper what was your setup and fuel at 19lbs?

I agree . To be safe, that 589 run A/F line should be the same as the 547 run and I would even have it around 11.5-11.8 for my sanity. Little lean in the upper RPM's for my taste. High RPM's + lean = too much cylinder heat. Not good.

As for the 3.25 upper and 4lb lower, I ran a 3.20 upper and 4lb lower and made about 19psi on a Gen1 Whipple with LT's. A Gen2 might net you a little more. You can get a pump gas tune on 19 psi just make sure your A/F is fat and you don't run too much timing.

11.4 A/F. Not sure what you mean by "setup"?

I think he means what combo ( upper / lower ) add on parts and what fuel you are running for you 19 psi ... also timeing and such would be a good to know as well

Im running 3.5 and 4lb lower on mine but im only seeing 17-18 pounds and i run pump gas most of the time.. when im really going to rag on it i put torco mix in.. I have not had any problems .. my A/F is 11.5 ish on the dyno .. my wide band reads like 10.80 -11.2

2.75 Upper/ Stock lower (Gen 1 W140ax). 16.75 degrees timing, 93 Octane. Dyno reads 11.4, wideband reads 11.4.

FPDC is 80% Max @ 6400 RPM w/ Fore Hat, twin GT pumps, wiring upgrade, dual FPDM's, -8 line to the rails.

Interesting,stock cop`s made a little more than the Accels.Agree w/above,a bit on the lean side.

 

[Vmnous285]

thanx guys I will call them today and ask them about the car being on the lean side. Yes COP's are a waste of money (Atleast Accels). I cant speak for any of the other ones.

Awesome pics. Weird, but that showroom area reminds me so much of a shop that was located in Wallingford, CT up to a few years ago. Very similar in layout. Is that a Cobra or a Roush Mustang (GT) in that second photo. Looks like a Roush side exhaust but I don't see any decals. Nice looking car.

Awesome numbers you made on the dyno! :beer:

Thanks! The car in the second photo is a 01(i think) Cobra with Roush body kit.

 

[CobraBob]

So the motor in the Cobra with the Roush trim is not Roush modified? Just curious.

So what were your numbers on this "setup" I am interested in going TS this fall and wonder. I don't know why but lately it seems the KB cars are making more power. I thought Gen II Whipples should have no problem getting into the 600 to 630 range with supporting mods, such as the OP.:shrug: What's the deal?

You can run that on the street but you better have some common sense in doing it. No back to back runs and some timing pulled. Then a very safe a/f ratio also. I ran it on mine for a while last year.

The OP is running pretty low boost really. Crank the boost up and it'll be over 600 easily.
