On a basiclly stock tpi intake, everyone nows it cn't breathe past 4800. what if you added a 6-9 psi supercharger? would that effectively increse the rpm of the power peak? Im lookin into a vortech s trim and i was wonderin if it would allow mw to rev to 6000 or so and still make power? thanks for the help guys.

 

Yes, this is what happened to my Crossfire then I added the Vortech supercharger.

Yellow is without boost, blue is with boost.
This is rwhp and rwtq numbers.

Could you add a little more clarifying info to the graph please.

Maybe use four colors and an legend. It's a little hard to read.

The yellow is torque and the blue is hp, but you have the wrong scale for the torque. If you use one scale, hp and torque (ft*lbs) intercept at 5250 RPM.

Thanks

The lower scale is RPM
The left scale is rwhp and rwtq

The two yellow curves are without supercharger.
The top yellow one is rwtq. It is something like 240 lbs ft from 2750 rpm to 4500 rpm.
The bottom yellow one is rwhp. peaks with 185 rwhp at 4250 rpm.

Blue is the same stock engine with supercharger.
The top one is rwtq. peaks with 350 lbs ft at 3750 rpm.
The bottom one is rwhp. peaks with 295 rwhp at 5250 rpm.

Thanks for clarifying, but something is still funny.

HP = Torque * RPM / 5252.

So when RPM's = 5252, then HP = Torque.

That is not the case with your graphs. The torque values seem way low.

 

You must read it wrong ...

Both the blue curves intersect at 5252 RPM ( 295 lbs-ft , 295 hp )

Both the yellow curves intersect at 5252 RPM ( 150 lbs-ft , 150 hp )

With the supercharger both hp and tourqe is almost doubled at that point !!!

yes boost will raise the rpm capability

i know someone with a STOCK INTAKE, RUNNERS, BASE on a 383 and a S-trim making i think like 18lbs of boost and he is going 10.70s on motor

then he has a two stage n2o sytem that has him go 9.60s

all through the stock intake, runners, base

 

I got it now!!!

Yellow top is torque, yellow bottom is hp.

Blue top is torque, blue bottom is hp.

A legend would help tons! And me reading thru your post better. LOL
