I'm going by Mazda Comp's estimate of 750-850fwhp which they based on Jim Downing's setup as it is very similar to mine. I also belive this to be overly optimistic, therefore I posted a HP range, and not a specific number. Also, I failed to mention that the engine will get a street port upon rebuild.

From what I understand, our dynos are a bit different from those overseas, but I'm not sure how, or if, that affects the numbers. Since I am not in the automotive business I am not building the engine to a particular HP target, so it will get whatever it gets. I'll be sure to post the results once the engine is operational. Right now I'm hoping to get it running by the end of March.

For what it's worth, MAZFIX's Drag FD is running a triple spinner with ports only fractionaly larger than standard and it is making 863HP at the flywheel at 18psi (no NOS)

Well I spose it comes down to what dyno and how much accuracy we are talking, and it is "ported" so how much is fractionally? but still 863 HP from a 20b!!! Yikes! what times and mph is this thing running?

Far as the dyno goes, We will be using a DynoJet Dyno for the to the wheels #s. Also the numbers quoted to Evil and I were to the flywheel. To the wheels should be lower obviously. MazdaComp was thinking with the setup put together, If I get it tuned correctly, it should have 850. I also think that is a LOT. But 500+ should be a sleeper to achieve for daily driving.
Far as March... (Fingers Crossed) Working my *** off. Milling Thermo-Housing tonight, after working...

in regards to MAZFIX's FD Drag car. You should know you are the aussie, not me. I think its fastest run so far has been about 8.2 at somewhere around 150-155mph

Sorry didnt think you would be talkin about that Mazfix, assumed it would be American cars you would be comparing to (dont know why)

I thought that Promaz were beating them using a 13b?? or is that all changed again?

Crispeed,
Ari lost in the semi because of traction problem at the middle of the track. There'll be a IDRC coming up in about two weeks and I'll be there hopefully running high 10's on Drag radials

Guys I have a question. Which spools faster a T66 or a T78? Oh, and which makes "more" power overall?

------------------
93 Silver Touring
Bonez SS DP
Bonez SS MP
Pettit ECU
K&N Intake
Manual bleed valves
Silicone vacuum hoses
Autometer Boost gauge
Autometer Air/fuel gauge
and 13psi of PURE FUN!

First a T78 is a Greddy,and a T66 is a turbonetics.They are both very simalar in size on the compressor,but the spool time all depends on the size of the exhaust(turbine)wheel and the size of the exhaust housing and also back pressure in the exhaust system.
