Will I make 300rwhp?

[Lebedin8654]

Hey how is my combo looking? I know its a little miss matched cause its mostly just thrown together. Here is what i have...

94 GT 5 speed
Windsor JR. heads they have some bowl work, the intake side has been cleaned up and i will port the exhaust side out some
Edelbrock Performer 5.0 intake
BBk long tubes
TFS 1 cam with either 1.7rr or 1.6 non roller i have both!

Would this combo take me to 300 rwhp or should i switch to a Trick flow intake to help it all match better?

I am looking to get 300 na and 400 plus with a N20 shot...

Thanks for any thoughts!!!

id say prolly 270-280 is a more realistic number.... id use the 1.7 rockers instead of the 1.6.... just my .02

Just put it together and drive it and enjoy it. Numbers mean little, and switching between a performer and a TFS intake isn't going to make a huge difference.

I hope you don't touch those heads unless you know what your doing.

Going in the ports with a grinder and going at it is not a good idea. You need to know what you're doing with a sbf head.

not likely unless you start getting creative

what are a few things i can do to help get me there?

And as far as the heads the bowl work was done perfesionally and the intake runs have been smoothed out a little. I was just gonna clean the exhaust up some...kinda gasket match it with the headers!

clean out some of casting flash on inside of the headers so that its smooth
a crank scraper
anything that rotates make it light as you can(aka harmonic balancer, crank, pulley's driveshaft axles gears etc etc)
vacuum pump

As mentioned above by lafenatu, don't touch the ports unless you know what your are doing. I have flowed heads to see what happens to the flow when the common 'gasket matching and smoothing' is done. Well, to start, removing the bump in the top of the intake port and making the port match up all the way around to the gasket, lost 10 cfm of flow on the bench. Other guys that ported their heads, even just mildly, lost 20 to 30 cfm of flow by getting in and not knowing what they were doing with the heads. Just leave it alone. It's not going to make much power anyway on those heads. If you want 300 rwhp, then just sell what you have and get a proven combo that will make 300 rwhp time and time again no matter what. Otherwise, as Paul put it, just put it together drive the heck out of it and enjoy. It sounds like an interesting combo that not many people use, so it will be different, and that's 25 rwhp in anybody's book

okay scratch the porting...should i at least go in there with my dremel and clean everything up? just kind of polish the runners?

 

[NXcoupe]

If you use a cartridge roll and just smooth the top and sides of the port, and don't shape it. don't touch the port floor. Then yeah, that helps with a few cfm. Best things you can do are the cam and the intake.

What a lot of people dont realize either is that its not about enlarging the port. You make power with velocity and that is where you really have to know the do's and dont's. The faster the air can get in and get out, the more power your going to make.

I have a friend that used to do port work professionally and now does it on the side. The stuff that he knows is just amazing..
