I'm disappointed with the results. Is that the stage 1 kit with a 8 psi pulley? I know your running the LTH's too ... but damn!

I hope the new dyno shows better results ..... but damn!

Going to install the stock headers and a high flow cat with CBE and see if it improves?

That is on a Mustang dyno that reads much lower than a DynoJet

I beg to differ, this is actually a great starting place right now.
The car is running an 8PSI pulley, combined with the long tube headers and aftermarket exhaust it is opening it a lot. Hopefully we can get a smaller pulley soon and jump back on a dyno to see how things improve when we run the car all the way up to 8PSI.

I know many of you want me to just throw back on the stock manifold and cats, but that is not going to be what is happening.
This setup is working very well, we are running an 8PSI pulley which was designed and tuned for stock manifold and cats. Nothing is disappointing or "wrong" currently, this is about what I expected with my setup. This puts us in a great position to work on this car and provide the best possible setup for what we have, and improve this platform beyond what anyone was expecting.

My setup from the start was not going to be an exact 1 to 1 copy of what GTM is producing. I have decided to go my own route with the long tube headers, and Sam at GTM is helping out tremendously on this and we hope to move forward with some great results soon.

It does sound like a good plan and I wish you all the best in your results.

I am following this thread closely because this is the direction I wish to go too ...... if I EVER get delivery of the SC before the end of summer.

Out of curiousity .... what is the diameter of the 8 psi pulley? and I'm assuming this is the stage 1 SC?

Thanks

not bad numbers for only 5.5 psi...headers coming off now?

No, Not until they figure out exactly what is going on and why the psi is low.

I told you rednek01.....Welcome to the world of VQ motors!

The 350z, guys were lossing 1lb or 2 of boost when using high flow headers. So why would the story not be the same with the VQ37, it is.

Boost.... pah, just get a big American V8 and drive on.....

Dreamer - Get back to work, your boss is pissed at you for the amount of time you spend on the phone discussing LTH and Supercharger thingimijigs......

LiquidZ

Adding headers increases your volumetric efficiency, which in turn lowers boost WITHOUT a loss in power. I'm still lost on this GTM + LTH issue.

sounds similar to what happened with Shumby's car, so I think a good place to start woudl be to work with their results first and see if putting stock headers/cats back on brings the boost back up.

I'm not saying it's the RIGHT solution (those headers can't be causing it directly), but it would be a start.

thats one way the other (easier) way is to use a different pulley on the supercharger and see if they can get the boost numbers to pick up.

Also It would be nice to compare graphs of this run and a 370z with stock exhaust and this supercharger. Just to see whats going on

true, if they have another pulley readily available to test in the shop.
