Unfortunately us mere mortals have to pay for our stuff. You, on the other hand, are SPECIAL, therefore we can only aspire to be like you......

I don't recall that in the 2012 rules. Bummer!

Remember that if you ask Greg a question about it on the forum he will ban you a potentially threaten to revoke your NASA membership. lolol

Modification of the OEM roof line is permitted, but will be assessed via a

That's 5% more weight :(

I would rather take a HP hit than add weight. Maybe a mix of the two.

Arrogant Douchebag problem?

Or maybe he's been getting so many annoying e-mails for so long that he just can't handle dealing with people anymore.

They are really sensitive on the forum though, any bit of criticism (constructive or not) towards NASA is locked down in a big hurry.

Checked through this thread and didn't see any info on the exhaust. Would you mind sharing now that it will be revised with the turbo? I'm curious about the details chosen when you get into 180whp range N/A.

It looks like an RB header and I'm guessing somewhere around 2.5"?

OTS RB header. We now thermal coat the exterior of the header and midpipe. Far more durable and easier to work with. Exhaust is a proprietary Supermiata "Laguna" system. Our cars are weight capped so we have taken to building very robust and super quiet exhausts for the race cars. Noisy exhausts increase driver fatigue. With a stock long block, the Borla XR-1 race exhausts work well and are a good OTS option.

Emilio, who do you use for the coating? Swain Tech? Or?

I've got to replace the 1.6 now, so I'll buy a decent (JR/RB) header and have it coated vs wrapping it.

When it becomes an ST2 car it will have the OEM roofline. Too much weight to forfeit otherwise. Just being 900# lighter than the Vettes will earn about a .5# penalty already.

Whole thing weighs maybe 4lbs. Nuclear defroster.

I know this is a super old post, but do you run water through the defroster all the time, or only on rainy days? i.e. did you put a bypass in the two hoses at the firewall to block off the heater core?

I hope to copy something similar to this for my car in the near future.

We tested our a square top and stage 2 Integral BP6D cams (I266° seat,.395cam/E263° seat,.385cam) in our CNC head two weeks ago. E85 with 83.5mm 10.4:1 Wiseco pistons, Skunk2 TB. We started to hit the limits of that cam and square top intake manifold combo. You can see that in the red plot where it flat lines. We have seen this with other race cams on BP heads with an STB. So we fitted some 45mm TWM ITB's we have had laying around the shop for a while and made 183whp, no other changes. Closer but still needs more cam so we pulled BP6D head off and replaced it with a BP4W CNC head with cams that have another .032/.025 more lift and 12°/3° more duration. These are the same cams we made 182whp with a square top and pump gas last year with. Hoping that will get us to our target just north of 190whp.

Square top vs ITB's: Note how the numeric hp gained up top is slightly less than the losses down low with the ITB's. This is to be expected for ITB's vs a single throttle manifiold (STB). Overall though, the power area is greater with the ITB's, just shifted up about 500rpm.



So for street, autocross, turbo, HPDE builds the STB is still the way to go. The PTE cars run a 5 speed so bigger gaps between gears require a broader powerband. Crusher runs a 6 spd x 4.3 so our gaps between gears are easily managed with a narrower band. The weaker low end power is not a concern because I don't have to race anybody in the pits. Monster torque would be nice but it's not possible within the rule constraints.

I'll try to post dynos of the BP4W CNC head and bigger cams in this pic before we leave for NASA nationals tomorrow.
