Since this is a Race-Prep block (designed and built for a twin-turbo application)...I don't know??????? I think that as long as I don't run 3bar all the time...it should hold up fairly well...there is one way to find out ...

 

2200 is quite a bit of ponies, if you ask me...:P

 

Chasen,

No doubt ............. alot of ponies for a brief moment. High boost creates heat in the charged air. Heat robs power rather quickly. In a straight line run for a brief moment you would be fine, on a track or held over an extended period you would lose over half of your power to heat. The trick is to make as much power as you can at a lower boost ............ say .8-1.0 bar ideally or 1.0 -1.2 bar at the most. This is what really drives up the costs of a good motor (more power at lower boost.)

Just my two cents.

 

As an update, we will have some real intersting pics just prior to Christmas.

 

Nice topic!
I'll bet that the 2.0 Bar they're referring to is absolute. With 2.0 bar of boost on top the 8.62:1 c/r and the V10's already large displacement, 1200lb/ft would be possible, realistically and reliably. With those big GT-45s holding almost all the boost, close to 11000 rpm, maintaining nearly 1000lb/ft would be adequate to yield 2000 hp.

Nice! (said like Borat)

As for the ability to use it, anyone who has operated high horsepower cars, motorcycles, boats or airplanes, knows that there are some conditions where even a real hero can't apply full power. However, there are those high speeds, where another 300 or 400 horsepower can come in very handy!
Finally, as for reliability of these super high-powered engines, they sort of take care of themselves, since, other than Bonnevile or Muroc, there aren't many place where the throttle will be held wide open for sustained periods of time. How long does a winning 7000 hp dragster engine last? 5 seconds, or something before catastrophic failure or complete rebuild.

I'll tell you nothing is easy. I wanted to go with the Dysan Carbon Fiber wheels with center hubs. They can do it in center hubs, however not half sizes so we can't get 10.5's. In addition. we would like 12.5's but again no half sizes. Currently the largest size they make is 11's, no 12's but they are saying 13's night be available aometime around March of 2007.

Nothing is easy with this project.

 

I'm guessing you already know of them, but have you tried?:

Saw them at SEMA and they were very nice. But other then that, I have no experience with them.

 

They are the distributor for the US. They are the ones who supplied the information.

 

Anyone have any ideas what the following tire choices would do to the handling?

Fronts - Michelin PSC's 305/30-19's. They have a 26.2" outside diameter and 791 rotations per mile.

Rears - Michelin PSC's 345/30-18's. They have a 26.3" outside diameter and 790 rotations per mile.

The OD and rotations are made in heaven. What will be the effect of 19's in the front?

 

I've done some quick calculations and have come to the conclusion that it will look goofy!

 

From a performance standpoint, giving the wheelbase of the 996tt, I think that you should stay with a 18inch rim....also, why so wide????? that will just slow you down...

 

VR, we are having a real suspenion geru look at this right now. As far as set up, we are not looking for top end speed. My two favorite local tracks are Infineron and LS. In addition I love roads like Mt. Hamilton, Highway One etc. I want this car to hug the twisties.

We don't want a wide body for the looks, we want it for the handling performance, if in fact it can improve this area.

If you look at our engine build, you will see it is a compromise between power and quickness with the edge going to quickness (Less weight many times reaches a limitation point power wise.) As in quickness coming out of an apex. Everything from the clutch, flywheel, crank, journals, rods, wrist pins and pistons were designed to eliminate rotating weight. The idea being less rotating weight allows the motor to accelerate faster into it's maximum torque rpm range. This is what pulls you out of the turns. This is not for a very long period of time, therefore you need to make the of this time through the engine response.

 

Chad,

Will S Car Go be doing the fabrication/installation/painting, etc. of the wide body or will it be somone else?

 

Great game plan....just keep in mind the c/d factors as to contact patch as well as wind resistance! Looking forward to the day of breaking into new record territory with her ....had a nice long chat with Todd today about your final engine set-up.....talk about a new envelope !!!

 

Our fuel requirement have just been determined for this motor. It is 900 pounds per hour which translates with overboost into 174 pound injectors. The pumps and injectors are being built and we should have them by January 15th.
