say you have a motor with peak hp at 4,300rpms and peak tq at 3,300rpms. what adjustments could be made, given that the valvetrain and bottom end are good for 5,600-5,800rpms, to move the peak hp/tq to the right? as in, a classic "truck-motor-in-a-car" situation.

long story short, if you had a powerband that you wanted to spread out over a larger rpm spectrum, what is the best way to go about this? my only thoughts (cheap fixes, not something $$$ like new cams) were to open up the exhaust. the hp/tq ratio is heavily biased towards tq (310hp/425tq), which isn't something one wants neccessarily for a car. if tq is sacrificed, could a wider powerband and higher hp be attained?

retard cams

what intake are you running, The truck intake will hold back the rpms if you have that.

Only true way to change the powerband is going to be camshafts and possibly an intake.

longer intake runners.....

IE intake...there really is no CHEAP way though. Retarding the cams might work, but it'd be making the car run less efficient and would show losses in both hp and tq.

the stock intake... long runners. for a street car, would a single plane high rise intake work fine to get the powerband more level and usable, or would a dual plane be sufficient and not give up as much tq?

wouldn't longer intake runners generate more tq? short runners = higher rpms/hp, correct?

i haven't found an aftermarket intake yet that will get the motor more car-friendly.

higher flowing heads , more lift and duration in the cams , high flowing intake/t-body and exhaust with a little extra compression and you should be on your way ............

longer intake runers will not broaded the curve it will lower the rpm peak power is made at and increase the toque

retarding the cam will shift the rpm that peak power is made at upwards and lower the low end torque some what.. so that is about your only choice unless you want to properly match parts IE intake and camshaft to the rpm you wish to run.

that's all well and good, but i am looking for a relatively cheap fix at this time. that stuff may or may not happen later, but first thing's first...

what is your opinion of a motor with 310fhp@4,300rpms/425ftq@3,200rpms? i realize it isn't like it's undriveable, but would you suggest retarding it anyways to be more enjoyable to drive on the street, or leave as-is? as the motor will be out, i'd rather make any changes i can now. thanks.

I don't see it happening ......

i figured it was worth asking.

well I am on my 14th car and haven't found any free or cheap horse power yet.....let me know if you do though....

knife edge your throttle body butterfly, cut down the little bumps on the shaft that holds the butterfly, and p/p your intake if possible... deburr the rough edges and gasket match. weld in a cut=out for the track... what else? clean your MAF. relocate air filter to fenderwell or just away from the engine bay. that should all be worth a few hp.

not looking for extra hp, i'm looking for USABLE power over a larger rpm band. redlining at 4,500rpms is not what i want from a street car. in fact, i'd gladly take a 20 hp reduction if it could be stretched out.

Add some nitrous to it and call it a day .

[thunderchicken]

Just keep in mind that when you make cganges for somthing your trying to do,you may loose something else,example...if you go for torque,and hp to a higher band,you may loose it in the lower band,where some of the time its needed,but i guess it just depends on what your looking for......jusy my opinion....

[95 GTS]

from looking at what you are doing....

retard the cams for now,

that intake is designed to peak that low though, so you might not go off and just do this. Its all designed to make torque in a truck. You can test it out though and see if it is the intake that will hold you back.
If they cheaped out and copied the I intake and added 2 cylinders like they robably did, then you will bein good shape.

Then call Comp. I dont see any reason they cant grind your cams for the future.

The car needs ported heads, custom intake and cams in the future to mae the swa actually be fast. and it will be cool.

Since when does the Air Force have a combat forearms course? I talked tillI was blue in the face trying to get authorization and funding for firearms training OF ANY KIND when I was at Lackland and overseas in Germany. All we had was smallarms qualifications once a year wheather we needed it or not. We qualified with the 1911 45ACP, the M1A Carbine, the M1 Garand and sometimes with the Browning Automatic Rifle. We also had EOD qualification once a year and that was it.
