Hey Alex, have you posted up that 21psi dyno sheet yet? 440RWT is awsome!

The torque on that run on the video was incorrect because the pickup for the dyno was not working properly. I believe it was around 360 rwtq but I may be wrong. Alex got the dyno sheets.

I should have known something was up, the math doesn't add up for a rotary. If he had 480hp and 440tq that would put him @ ~5700rpm for peak power. With 360RWT that put's him at 7000rpm for peak power.

Yeah, when I first made the video, I used the torque from the dyno's monitor. Cris later pointed out to me that it would likely be off due to a spike. The dyno sheet I have for the high boost run doesn't have torque or RPM listed because the optical RPM sensor that we had to use was a fluttering at high RPM.

The car does make power to redline and beyond though. The runs were done in third gear.
Also, remember boost dropped slightly toward redline, and we need to change the WG spring.

Sorry, I must have missed the post.

I did not "blow" the stock one. My 1st time at the track I bent the axles on my first launch with regular drag radials. It kept leaking fluid afterwards through the seals.

If I would have kept on the street tires (read: Absolutely zero traction), it would have held fine.

This one is very heavy duty, and just plain heavy. It has custom Strange axles, 9" Ends, C-Clip eliminators, big bearings, 31 spline, Auborn limited slip differential with Ford Motorsports Gears. It really is overkill. This wasn't what I originally wanted, but the installer just did his own thing, without asking me or my tuner our wants. It was a real piece of ****, that Crispeed ended up correcting in the long run.

It's still not finished & as I haven't put many miles on the car. The rear brakes are probably going to be swapped out for smaller ones, as the current rear brakes are are locking up before the front, no matter what we do.

Oye pendeho,

You plan on painting that thing any time soon?

That thing is a beast... Almost as fast as the Noid...

Heh heh heh...

Shows you what you can do with $125k and some time!

Seriously, very sweet. A dream come true. It has come a long way from the cardboard and duct tape control panel and Peo's shop, eh?

A Long way. Leo passed away a couple of years ago. Give me a call. I called your cell on you B-day, and couldn't even leave a message.

The cubes are pretty common but the IC's normally find a way of hopping out before they hit the yard.

You can usually find them on Ebay http://cgi.ebay.com/ebaymotors/Honda...spagenameZWDVW DirectFreak which one do you have? There are 2 different "large" NPR intercoolers one is 14.5in tall and the other is 16.5in tall and painted black. I have the smaller of the 2 large intercoolers and was wondering how well these performed.

I've tested many core design/sizes etc. One of the best setups I've ever used was joining two of the black cores, front to back together.

Yeah I thought about doing that but man it's hard to find space in a Datsun 1200. Would you happen to have any pictures of that intercooler setup? What's the threshold on horsepower for the NPR intercoolers? I've heard 450rwhp but I've also heard of guys making past 500rwhp on an NPR intercooler on C16 fuel.

You mind me asking what was the best core you tested? Was anything better than 2 black NPR's? You just cut the endtanks off and weld on custom tanks that joined the 2 cores together?

Hey Chris you should put your contact info in your sig so people know how to get in touch with you if they need your services. I wouldnt mind going down that way for some tuning later this year.
