2010 Time Trial S NASA National Champion!
I just got back from Miller Motor Sports Park in Utah where we just held NASA's 2010 National Championships. I am the new TTS NASA national champion! The track felt slower than last year but everyone had to contend with the same conditions. I ran under the team name "Team Howard Racing" and won with a lap time of 2:03.5, second place was Tage Evanson in his dual wing supercharged Honda Civic with a 2:04.0, (some people know Tage from Time Attack), third was Jeff Sawtelle in his C5 Z06 Corvette with a 2:04.1. Sawtelle ran a 2:03.9 but his session was DQ'd because he came in under his minimum weight. Sawtelle was last years TTS champ, so it was good to beat him.
In addition I also placed 2nd in the Super Touring 2 race class behind Ron Farmer's Corvette C5 Z06. I had a chance at 1st but I went into the race with a weak brake pedal, (I think I need to replace my brake master cylinder). I was catching him towards the second half of the race but they threw the checkered flag 10min early because of too much debris on the track. It was suppose to be a 45min race. There were 23 entrants at the beginning of the weekend, 16 made it to the grid for Sundays final race. I feel pleased with my second place finish, although 1st is always better!
Depending on finances next year I might return to defend my TTS title and have another shot at the the ST2 win. Next year's nationals will be at Mid Ohio.
I will have updated dyno sheets and hopefully pictures to follow in the coming few days.
Cheers!

Many of you know I've experimented with a couple of intake choices, all using my Motec FI. I ended up puting the 3rd gen upper manifold mated with Ground zero lower manifold that has been shortened 1.5-2". This was my first setup only without the shortening. We made 243whp and around 158-159ft/lbs torque on a dynojet, SAE corrected was 238 and 155 respectively. This is with a small 4 port bridgeport using a 3rd gen block and 89-91 RB rotors and ceramic apex seals. Peak HP came between 8k-8.5k (pretty much a flat line between the range). We were letting off the dyno at 8.7k, but we did several pulls early on to 9k. This has been the best compromise so far for HP and torque.
Minimum comp weight with driver: 2280lbs
Maximum SAE corrected HP: 239whp
MODS:
RS (can't mention his name here) custom stainless exhaust
RS modified Ground zero lower manifold
2nd gen coils with MSD wires and Digital 6 box
Motec FI
Underdrive dual pulleys
Quartermaster 8lb flywheel with counterweight
Quartermaster 5.5" dual clutch
Quaife close ratio 5speed gear box
4.88 or 5.13 rear end ratio (depending on track)
7's only front big brake and bearings upright kit
Koni double adjust and revalved shocks
Custom tubular adjustable front swaybar
Trilink rear with panhard
Hawk Pads
Mazda Comp Drysump Oil
Ground Control rear collars
FR 700lb/RR 500lb spring rates Hypercoil/Ground control/Eibach
7's only ackerman arms and 2" of turn in spacers
16x11" CCW's with Goodyear 23.5x10.5" slicks

just looking at the pics, the lower intake puts the upper further forward, and it makes it look like you could move the engine further back?

I'd like to run forced induction and run a class higher, but it's to much money. If I move to ST1/TTU class I would be allowed to run almost 340whp, that could also be a Peripheral port or D bridge.
I'm thinking about buying a dog box with straight cut gears next year.
Another problem I have is chasis flex in right hand corners, my right side rear tire wants to lift off the ground under extreme cornering loads approx 1.4-1.5g's. Regardless of my LSD, the inside right wants to spin delaying the time I can get back on the throttle.

This is true, we've thought about doing that, I'd have to modify some mounts and have a custom driveshaft made. This may happen in the future! We've already lowered the engine and tranny lower in the car because of the drysump.

I've refined a few things since this graph. I adjusted the fuel in a few areas to get the AFR's more consistent. Mainly after 8.5k and before 7.5k.
Also, Robert said he was letting off the throttle at 8700rpm since the power peak was between 8k-8.5k.
