Yup, just 52 pph injectors.

I didn't mention James Reeves car for that reason, he is using a 5th injector as well with his 350+hp 2.5.

Kevin's car @26psi is very close to the power output of Steve's car. Both cars are about the same weight. Kevin's 1/8th mile et was only .2 slower and the mph is only 1mph slower than the 11.8 @ 118 pass that Steve has posted. I wonder how close are the 52's to being maxed out at this power level?

2.2 or 2.5?

[kedavis]

its a 2.2 i actually got the performance data off your sight gary to figure fuel pph.i believe i could run more boost but my duty cycle is getting around 97% at 26 psi.i think if i was running on a 1/4 mile track i may run out of fuel on the big end.

Your already @ 97%DC. And going from 26psi to 30+ is going to be quite a few more oxygen molecules to try and burn!

Reeves ran as quick as 11.42 and as fast as 123mph without the 5th hooked up. Race weight is 2450 with him. Boost was approx 26-28psi based on the scanner results. EGT's were 1700. The 5th is now set to come on at 25psi. Egt's back in the 15's

That's hauling some toasty butt!!! I wonder what his AFR was at the 1700deg temps?

Considering the tbi cam has .040" less lift on the intake & .020" less on the exhaust, it ain't bad for the $$. Now, if only there was someone willing to let me try a prototype high lift roller

I thought all stock rollers were .430" lift both sides?!

They are. I was referring to the Taft S2 roller cam which has .470" lift on the intake & .450" on the exhaust.

Oh

Finally got to revisit these posts. Nice dyno numbers and I'm sure there is more available with some fine tuning.

I can't find specs for the Taft S1 camshaft anywhere. Dennis Dozas site used to have them but the whole chart has disappeared. Cindy's site had the the specs listed until they stopped selling them. Does anyone know what they are?

[John B]

Never mind, found 'em at Taftcams.com.

sweeet.. i have been wondering where than domain name was hiding lol

But the site is missing pricing.. but i enjoyed the honesty of the site showing its results and how you should expect to lose low end power [20-30ft/lbs] with the staged cam's over the OEM unit, but gain better mid to top depending on which stage you select.

I still would like the S2 to attain my goal of high 13's on 15 pounds of boost.. but im wondering about the F2 and F3's Cindy is offering now..

I LOVE the choses we have now for these motors

we should start a thread with experiences with these 3rd party cams!
