That is excellent news. I really hope this kit works out for you with at least 12psi as I'd like to put together a similar setup for my car.

Thanks Bro! That Ferarri Red paint is expensive, but worth it. :cheers: :cheers: Here's a better PIC.

 

Long tubes and a Cam with a bit more Duration/Exhaust Bias may help.
Do you have either right now?

Hi-Flow Cats could help too, or no Cats.

This is a Twin setup, so a merged downpipe restriction is not part of the problem, eh?

 

I'm with Jeff on this one who knows this may develop into the package everyone is hoping for--good luck Bill

 

:iagree:

 

I am sure that you guys have looked at all the options. But I would like to mention that if you guys are using single solenoid boost controllers you might try going to dual solenoid boost controller as it would allow the wastegate to stay closed longer(2 solenoids controlling the wastegate instead of 1). The specific model that comes to mind is the Blitz Dual Solenoid Boost Controller. I remember reading an article comparing various boost controllers and the Blitz Dual SBC came out on top as it controlled boost better as it kept the wastegate closed longer. It also picked up power in the midrange band. Just thought I would mention it.

 

Good to see Bill Reid making it happen.:)

I've talked to Bill in the past a few times and he seems like a real honest, can do guy, who cares what the customer gets in the end.

Hey Kevin, good to hear that things are going better. Can I uncross my fingers now? Prayer does help!! :blueangel: :cool: :blueangel:

 

:thumbs: to everyone that came back together to get this one working.

I was like wtf when all this lawsuit stuff started coming up. Glad to see it is all going to work out.

 

Hey Biglew,
You can uncross your fingers as to Xtreme, but keep them crossed for TTi it is still hanging in the air. Bill worked Sat. to put on the car back together, but it looks like the passenger side turbo needs to be put on today. Bill IM'd me yesterday and told me that the car should go back on the rollers by Tuesday. Lets keep our fingers crossed that the larger Turbine Housings will reduce the exhaust back pressure and keep the waste gates from popping open during any real boost...if the system can least hold 12lbs to 6200 rpms, I suspect the hp will get alot closer to the torque that is being made. 12lbs is still 3lbs off from what TTi claimed the system would make...but I think that if we can hold 12lbs of boost will develop some good hp numbers.

Lets weigh in on how significant it is to hold at least 12lbs of boost to redline...if it does it should make almost 600 rwhp (guestimate) it is already making 610 rwtq. Wouldn't it be nice to have a TT setup that makes 600/600 at the rearwheels for about $12K installed. I am thinking that it would be for a great deal a many reasons..competition like that might drive down some other TT prices as well.

 

just a thought... but if your having such a hard time getting 12psi out of these turbos may not be a good choice for this application. Usualy when a turbo is getting to it's max airflow it is getting out of it's good efficientcy range. Make sure you keep an eye on your intake temps because they might be getting pretty high.

 

Good to hear that things are still moving forward. I had said from day one that IF these are the same T28 compressors that they use on the Mitsubishi Eclipse's 600rwhp is going to be the MOST you can expect under perfect conditions. The engineer's at the company(Turbo Engineering Corp) that built the turbos told me that they were good to 700hp but he never said flywheel or wheel hp.

It has not been a compressor issue at all with these Turbos, I have seen the mapping for the standard T28 and would agree with you blowing hot air and only being good for 700hp, JPAS sent it to me a couple of months ago. However, according to TTi these T28's are hybrid (having larger compressor wheels, I don't know if the eclipse or 300zx ran hybrids or not) apparently they are capable of making 30+lbs of boost on the Nissan 300ZX...the problem that the kit is having on the LSx at high boost..is exhaust back pressure because the turbine housings that the kit comes with are apparently too small to support anything other than 7-9lbs of boost. ONCE AGAIN I am only reiterating what Jim (TEC), Jim, and George at TTi have told Bill Reid, Nate, Mike, and myself. Right now Xtreme is doing the R&D for TTi to figure out whether or not the this kit with bigger Turbine Housings will actually support the amount of boost and hp that TTi has claimed the kit would.

12k installed? But then my motor blows and I need how much more $$? Or do you mean having a forged engine is included in that price? :D :eek:

 

hmmmmmmmm...always knew I was going to be going to a forged bottom..never really thought I would stay with the stock internals because I have always known what kind of boost and hp power I would want.

For example if you buy a D1 and you put it on your car...you could run 7-9lbs of boost and be safe on the bottom end. Afer awhile you might get board around the 450-500 rwhp mark. Then you decide that you want to run 10+lbs of boost. The motor eventually blows or you decided to have one built before the inevitable. So new forged motor in and you swap the pully on the blower and you have 10+lbs of boost.

Now you buy a TTi kit, and you put it on your car and run 9lbs of boost..the motor never blows and maybe you are making 500/500 or 525/540 rear hp/tq and it gets old...so what do you do? The kit as is will not make anymore boost so you have spent $12K installed for no future development.

It becomes easier now to see the importance of having a kit capable of making 12+lbs of boost. It becomes more apparent now how important the work Xtreme is doing for TTi, me, and many others in developing a kit that is capable of making more power. Having a kit that is capable of making more boost..means you can purchase 1 kit, and that you are not spending the money on something that has no room to expand. This is why I participated in this project with Xtreme, I was told the kit would support 15lbs of boost and 600rwhp.

So to anwer your question...if all goes as planeed with the modifications Xtreme is having to make to the TTi kit to make more boost. You could purchase the kit, run a safe amount of boost, and then when you decide of cylinder pressure does, you can buy a forged short block for $3K and have car that runs like stock and makes (hopefully..fingers crossed) in the neighborhood of 600/620 rear hp/tq...

You would need a stroker with a large cam and a 100 shot of NOS to make that kind of power (600/620)...or a D1 with a 427 to make those numbers. D1's on a 346cid make about 545 rwtq above 4100 rpms. The TTi is making 610@2800 rpms. Magnusson and Strokers around 500 rwtq @3000 rpms.

I think that most who buy these poweradders (blowers, turbos) would like the satisfaction of knowing that there is some room for expantion. Stroker guys always know they can throw on some NOS and make up the difference when they want to expand.

So this is why it was very big of Xtreme to pick back up on the project and continue pursuing what TTi told them, and they told me. So "Rock On"!

Sounds like a great place to do some business.

 

I agree extreme really seems to have their "ducks in a row" so to speak.

All these problems remind me of the LS1 Motorsports vs TTi B.S. that was all over LS1.com 2 years ago.
