just added 4.30 gears and havent been to the track yet. i need to replace knock sensors and im moving over to speed density. im already running a 3600 converter and dont want to go any bigger due to a 125-150 shot out of the hole and another 100 to 125 shot at 2nd gear. im hoping the gear keeps me in the power band.

and i want to add one of these 102mm intakes lol.

very nice gains. I wonder how much you would gain from a 102MM throttle body.
And for us 78mm guys. I'd bet the gains would be closer to 35-40hp

I would like to see what it does out to 7k on a bit larger engine, but none the less cool to see the graphs and thanks to the original poster for sharing.

wow thats pretty sweet. even for 1k, that number would jump for the guys that have CAI/LT's full exhaust, cam, and tune to probably 40rwhp. id say that mod after what i listed would be a good upgrade since 1k is middle of the road before FI. good numbers!

because thats usually what happens...

4500 +3.5rwhp
5000 +17.3rwhp
5500 +20.5rwhp
6000 +19.8rwhp

4500 +4.1 lbft
5000 +18.1 lbft
5500 +19.6 lbft
6000 +17.3 lbft

Interpolating using the above data, there would be both power and torque losses under roughly 4000rpm.

Gains up top, usually always mean losses down low.

Nice baseline data.

Now, how much would simply a 102mm tb affect things?

And, any word on if they are coming with the RT for the rectangle port heads yet???
