Whats up guy's,

I wanted to let people know that I will be dyno testing a set of stock GSR cams and a set of Skunk2 Pro I's to see if there will be a significant gain with a Turbo street setup on 91 oct.

There has been some testing with some High boost applications on race gas and some great results have been recorded, but we have not seen anyone test with pump gas low boost.

I will be testing 14lbs to 18lbs on a Sleeved 84mm LS with a GT35R. Here is a picture of the engine that will be used. This car is driven on a daily basis and is running on 91 oct. I will be posting a full engine write up when I have the cam results. I will be doing this in the coming week.

I would also like to test with a set of type-r cams, So if anyone has a set that can be loaned out for this test, please PM me. That would be greatly appreciated.

 

You're going to see a HUGE gain over gsr cams!!!

 

<--- in for results.

after seeing your test, Im sure I will!

Im hoping for the same result...more power lower boost...that way these guy's on the street can have a more reliable setup at lower boost

How does more airflow with less intake restriction mean anything for a more reliable car?

 

is this in an integra or eg?

It doesn't....It's the boost level I was referring too.....the testing done so far on race setups show more power being made on lower boost rather then higher boost with type-r or gsr cams.

Tony1 has a great thread showing more power being made at 31psi on pro1's rather then 35 psi with typer cams.

If this is true for a street setup then someone that had to boost 16psi to make x amount of power will only have to boost 12-14 psi to make the same x amount of power.

that's all I was referring too

 

More boost generally means more exhaust backpressure and higher air temps, both of which cause detonation. Any time you can make the power at lower boost, it's generally safer.

 

My test picked up about 40whp with 3psi less boost. That's the equivalent of 80-100whp with the same boost levels.

good god. how much are these cams? are these the stage 1 turbo cams or just the normal stage one cams? cuz thats what im getting from skunk2.com

 

MSRP is $730, but some of us , can get them to you a little cheaper...

correct, you should be able to get a set of these cams for an avg price of $600.00 from any skunk2 dealer

But we are not talking about less airflow. We are taking the same amount of air, or even more, flowing through the very same hotside restrictions.

In F1 they use a restrictor that provides a definate maximum amount of flow. You can improve power by increacing the efficiency of the motor.

If you have a variable amount of airflow and you increase the power output, how do you know if the gain is due to efficiency increases or increased airflow.

If the cars produce more power with more air at lower IM pressure, I assume exhaust pressure would be higher also.

If the cars produce more power with the same amount of air...

Did i ever say less airflow?

It's more airflow, but at less boost. When a compressor makes boost, it heats up the air more and it has to work harder. This results in higher exhaust backpressure and higher air temps, both of which lead to detonation. 450whp at 12psi IS going to be safer and more reliable than the same engine making 450whp at 20psi.

 

When are you going to be on the dyno?

for results

I'm running ITR cams right now. I will probably try the S2's out myself and post some results. Smaller turbo then you or tony1 but pushin 500 already.

Clean setup btw

 

That bay is beautiful

 

In for the results.

I give props to anyone who is willing to do a comparison, and share the results.

If the difference between cams is simply moving the pressure ratio down, then the calculable efficiency increase will probably be tiny.

Is it more air? What if you put a restrictor pre-compressor that flows 400whp and swap cams, how would things change?

Sometimes when you cam a supercharged motor, your boost goes down and your power goes up.. but we all know the same amount of air is being utilized.

Is the cam upgrade allowing the turbo to do more or is it increasing the VE of the motor?

 

the tranny looks sweet as hell. also, the nuts on your shock tower, are they anodized or painted? ive been looking for anodized nuts and bolts but i cant find any

RHD...?

 

yes, real 4 door type-r
