more top end?

[ninety1gt]

what can i do to get more top end with out doing heads and cam?

 

[IntenseBlue]

A blower or some spray.

pull the timing cover and retard the cam 4 degrees.

does this take away from low end power??




since i dont have money for heads and cam. do yall think some 1.7 rr help out?

 

[Topdowncruise]

Not much since your heads/intake probably don't have the breathing to take advantage of the additional lift the 1.7's would give you.

 

[seijirou]

retarding the cam and/or going with 1.7 rockers will give you more top end at the sacrifice of bottom end.
That's just what happens when you open up the maximum breathing capabilities of a motor.
Power adders for the most part give you more power everywhere.

search ebay for used GT40 or even GT40p heads , and cam and new timing set doesnt cost that much ........trust me if you can find some heads for 300 - 400 bucks and then spend 200 on cam and timing set , once its on the car you will wonder why in the hell you waited so long to splurge and spend a few hundred on your car .......on a good day your car might put down 220 rwhp , dont seem like a lot but with used GT40s and cam 255-265 rwhp is a big big difference ......its almost as good as a 75 dry shot on a stock car ....but its there all the time

i was going to say blower. but if you don't have cash for heads then i doubt you have it for a blower. You could go to a solid roller cam and valve springs to match so that you don't have valve float at higher rpm's.

I was just reading your sig.
What is a tps enhancer?

I was just reading your sig.
What is a tps enhancer?

its made by caspers electronics, TPS voltage at Wide-Open Throttle (WOT) is a function of power enrichment (PE). If the voltage is below a certain point at WOT, the ECM will reduce the level of power enrichment and the engine will not perform to its potential. This device is completely transparent until 70% TPS, then it takes over and assures maximum TPS voltage for 100% Power Enrichment (PE) when you need it the most. The TPS TEC also corrects for low sensor voltage and "dead spots".

 

[seijirou]

Taking care of low voltage and dead spots is neat.

 

[ninety1gt]

yea the car felt more responsive

Would'nt changing the valve springs help the top end(valve float)?
I had a few people tell me that the stock springs are shot after 40k miles. Is this true?

 

[IntenseBlue]

I've heard that they take a **** quickly, too.

 

[Mark89coupe]

With the mileage I have on my car the power falls off at 4k rpms.

without proper valve springs you could be loosing a lot of top end power. always a good idea to have the valve springs that match the cam installed.
