997 TPC Racing Turbo Kit... Coming very soon! :p
We have no plans other than the hotter injectors that we have been running as of now... The stock fuel pump has worked to 500whp so far and we dont plan on running these cars past that.

Please tell me more about the "signifcantly more flexibility and support than non-TPC supercharger kit offers". I'd like to hear more about that.
Boost adjustment? We're only talking max 6psi still right?
With regards to power gains, it's not the supercharger that is limiting the power (there's plenty more there with a pulley), it's the engine blowing up that is the issue. How is it the the turbo car can produce more power than a supercharged car with stock internals and compression? What kind of consistent rear wheel numbers will this kit produce?
What kind of tweaking can you do? Again, it's only 5-6psi right?
I guess what I still don't get is why someone would tear off a kit that cost about 10% of the purchase price of the car to put on another kit that cost around 10% of the purchase price of the car.
Like I said in my previous post, if you were starting with a stock car that's another story. For the $24K the owner just spent on FI kits, he could have applied that to the revenue from the sale of his current car and gotten a turbo.
Looks like a fun mod. What is the cost for the kit and how will you support it for people that don't live near your shop?
I do applaud TPC for setting themselves apart from their competition by coming out with a totally different product instead of competing in the same arena. Good business move. It will be interesting to see how the kits hold up. We already know the engines will take mild FI applications.

Typically, a centrifuge compressor driven by the crank will give you approximately 17 rwhp for every pound of boost. Everything else being equal, a turbo will give you approximately 25 rwhp for each pound of boost. This is because, although installing a turbo does in fact use engine power to run, the amount of power used in far less that the belt driven compressor. Obviously, tuning, such as a/f ratio and timing will effect final hp production for a specific boost level.
However, all things are not always equal. Chances of the turbo producing higher intake temperatures than your SC is predicatable. Turbo will heat soak faster. Single turbo requires proper balancing of exhaust on the bank not driving the compressor.
For information purposes, the modified VF system has already delivered in excess of 450 rwhp on a 3.4 engine and with proper tuning, more is available. The system, however, is running more boost than TPC is with their turbo.
I suspect the TPC turbo will provide a nice alternative to those you do not want to supercharge their engine.

i think whats limited the SC kits from running most boost is the stock fuel pump and the 996 should be able to handle up to 8-9psi without any real issues if the tuning right
hey Casey, is TPC going to change or improve the fuel system delivery other than changing the fuel injectors? maybe a 5bar?

Don't believe rumors. The stock 996 fuel pump has more capacity than you could ever need.

I think that the TPC turbo IS running a Y-pipe so that both banks are driving the compressor,however,one bank is longer than the other.How much will this effect things,I would think minimal IF at all!
Let's assume your figures for the amount of RWHP/PSI of boost is correct.....than 6 PSI of boost would mean the TPC turbo would develop another 48 RWHP with the same amount of boost over the supercharger...!
That would be VERY impressive!

I am a lazy bone when it comes to logistics. it is really much less argument of kit/install price than nevessity to have to get time off work and family then drive car somewhere, then leave it there, fly back, then fly back again to pick it up... time is much more precious than money.
Still I am very interested to see how this project will work out eventually. Keep up good work.

This is the TPC turbo thread.....
Just my $.02
Stacy
PS sent you a PM

OH no NOT at all and I hope it didn't come across in the way that you needed to apologize!
I just want to let TPC have their day in the sun.......without confusing things for them!
Now to compare the two systems once the data is collected....Game on!

If you're measuring PSI going into the throttle body, wouldn't it still be 6psi regardless of how you're compressing the air?
Turbos are more efficient than superchargers, but aren't the blowers on the VF kit capable of moving much higher air volumes than 6psi?
Doesn't it come back to how much hp our engine can safely take, regardless of how you got there? Just because I could run 12psi with my blower doesn't mean the engine can take it. Right?
I'd probably buy the TPC kit if I was starting from scratch just because the air filter won't be such a pain in the *** to get to like on my car

Yes it does matter how much boost/power our engines can take(does anybody really know this number for sure).
The superchargers require our engines to turn the superchargers via a belt to make power thus robbing us of some.....turbos run off of the exhaust(waste) and DO NOT require nearly the amount of energy to make the same amount of boost.
So IF our chargers are making 6 PSI and make 17 RWHP/PSI of boost
And the turbos are making 6 PSI of boost and make 25RWHP/PSI.....
Than you can make more power with the same amount of boost.....on 6 PSI of boost...I am sure it will be substantial.
These numbers may NOT be exact but they get the point across.Hopefully I will be able to get one of these turbos to try my Gtech to get some numbers for us.
Another thing to think about IS the turbo kit comes complete with the exhaust....so if you are starting from scratch..that alone is a savings of $2500...because there would be NO need to purchase the high flow cats and mufflers separately...BUT please allow Casey to chime in and confirm this!
Sorry IF this sounds confusing...I know what I want to say but can't seem to put it into words!
All I know IS I am VERY anxious of the final results of this kit!
Stacy
PS I agree on the air filter too,BUT, after doing it a few times it has really become easy!
To be honest I have my Modified VF charger for sale as we speak and IF it sells,I will be buying this turbo set-up.And YES I would be honest of the results,like I was with the VF supercharger!(shameless plug,sorry),LOL

TPC will supply the muffler and possibly a high flow cat(1 of each) being the exhaust exits ONLY one side.The question IS....is this going to standard with the kit.....
Muffler would have to be forsure but the cat,I am unsure...CASEY!
