I'm not sure what I said was even correct. But this setup does seem simpler than the typical turbo systems I've seen. Yet, they all work the same way. I guess the difference is moving the components away from the cramped engine area. I don't know, I'm just thinking out loud.

Before I started this project, I was looking at the STS twin turbo "generic" kit on their website. In the end, I decided that I did not have enough time to install this before our 3rd Coast event. I was planning on placing the turbos where each muffler resides. If you remove the heat sheild, there "might" have been enough room. I will never know now. I didn't get to the measurement stage, but the twin turbos in the STS kit looked tiny compared to one 60mm unit.

Keep in mind, that for a few hundred bucks, an upgrade to a 68mm turbo is an option for the single turbo set up....... a 60mm is standard. This would only be necessary if planning on going into the 550-600 rwhp range......

OMG 68mm it is, woo hooo, now those are some numbers I like

And the total cost was what?

So now the question is SC or TC my shark. Damn this thread!!!!!!!

Oh nooooooo!!

Turbo vs. SC!!! JK!!

Kit cost was $5250.00

In order to get into that HP territory, much more money will need to be spent other than the $300 turbo upgrade. Bigger injectors, super maf or the super maf harness thingy, possible boost controller, methanol injection to control detonation, 9:1 compression ratio would be a good idea too, with stronger forged pistons, and on and on.......its a slippery slope for sure!!

Sale the headers if your go with a kit. It would sound amazing with the headers. But the heat and keeping the heat to the turbo is must to get the most out of the turbo. I have 4 years of running the STS on my GTO. I have done shorty headers, long tube headers and the stock cast iron manifolds. The stock manifolds with wrapped exhaust on a T-76 turbo have a quicker spool time then the smaller 60-1 turbo on the shorty headers that I started with. Back to lurk...

Slippery but well worth it

I was sitting on the couch last night thinking about turbo lag. I think the reason that I am not associating the performance of the car with lag, is because I have honestly not lost any power below the point at which the car just makes more power under boost. So, instead of thinking of it as lag, think of it as anti-lag, or anti-boost maybe. The car goes as normal below "X" rpm, and then just goes like stink after that. Having the turbo in-line with the exhaust did not slow the car down at all below the point of positive intake pressure.

The only time I notice lag, is when one of the boost tube joints pops loose under boost. This has not happened since I added the BOV by the way.......

Not sure why, but the phone number on P9's website is disconnected and my email's have gone unanswered. Does anyone know if they are still in business?

killav

I have John's cell number and can PM it to anybody interested in the RMT kit that he sells. Not sure about the number on the P9 website as I have never tried calling it.


Eric, PM sent.

John Speake

Mike, I have an email address for John, if you think he would want that avalable on the list ? Not a P9 one...

I don't think John would mind at all. Especially if it brings him more business.

I tried the P9 email as well, didn't seem to work.
