How is pressure being relieved from the crankcase when the engine is in boost?

This might help.

Good question. I assume it's being pushed out the open vent on the drivers side of the valve cover.

WOW, That is my dream car. I love the autokonection fast back kit......I would have that in a heartbeat if they were available here !! (New Zealand)

Stunning. :drool:

That's the first think I noticed when I looked at the engine photo.

I spy red prancing horse:

There's something entirely fucked up and wildly appropriate about a Ferrari engine sitting on an old, greasy wooden rolling dolly.

ZOMG! that's win. Such a shame it's torqueless.

You're right, it should be in the fucking dumpster. :fawk:

Stepping up the game a bit with some AST5220's. After selling my Koni Race suspension the total out of pocket was 2k. Too good of a situation to let pass so I jumped on it.


The car worked so well with the Koni Race setup I was reluctant to make the change. I opted to keep the spring rates the same as before (850/500). This should make for a well controlled test since it's the only thing being changed.

I added the zero rate helpers after the purchase.

Why didn't you do tender springs instead of zero-rate helpers?

That is a can of worms I would rather not open. I looked at the pros and cons of each then ran it by Tony. We arrived at the same conclusion. Not sure if it was for the same reasons because I did not ask.

The scary part of the change is the possibility of going backwards. This thing worked so well with the previous suspension Dean felt I maybe making a mistake changing it. When I bought the car I asked Tony what would be the one thing he would like to change. He said the suspension with AST/Xida. Got to say you played a role in pushing me over the edge.

My goal is to make it a ST2 class winner. Track record at Thunderhill for ST2 is a 1:50.8 using the bypass. Assuming the bypass is worth 2 seconds we are within 1-2 seconds of it before this last round of changes. It's all about the free HooHoo's.;)

People do crazy things for that purple crack :)

BTW....this looks like 2 b-series forged at the hip......

New motor with forged internals, 11:1 CR, E85, Ported head, ATI Damper, oversize supertech valves, Supertech SUB, custom web cams and supertech heavy doubles.

Rebello ported the head and assembled the motor. Trackspeed supplied the supertech valve parts. I spec out the cams, Tony at TC Design fabricated the plumbing, Intercooler, radiator mounts, air filter housing, Skunk 2 intake and tuned the car.

Looks like somebody wants to race from a roll.

It's not a autocross car. It's a ST2 car that lives between 5,200 and 7,700 RPM's. With 4:10's and 6 speed it always in the meat of the power band.

Looks like fun :)

What's with the loopy plot in the lower rpm? I haven't seen that before. I'd almost guess wheelspin..

The loops are gear changes. The light 5.5" unsprung carbon Tilton clutch is a PITA on the dynapac dyno. You can't really slip it underload and high gear.
