Took it to the drag strip Friday night. I did ZERO Prep for going other then taking the wing off. I showed up on the Race tires from sebring and found they only had 17psi in them and there was no place to add air so this was a Half Arse effort at best. Which was good because the drag strip had ATV wars going on and we were there for 4 1/2 hours and got 2 passes. 1st pass was rev limter in every gear and a really bad bog on the launch. 2nd pass I pulled a "better" but not great launch of a 1.99 60ft and still rev limited one gear. The issue was having to use 5th just at the lights which hurt the mph. 2nd pass was a 13.55 @ 102.8
Anyway View from a Friends 220whp S2000 (ported intake, AEM stand alone, CAI, Ported Throttle body, header, test pipe and 3 inch exhaust)

Your care pulls!! I havent launched my car since the FnF days!! lol What size tires are you running? I tried some 275/35/17s this last Saturday at the track.

Mrsideways

I was on a 235/620 R80 Slick. I did a decent burn out before the 2nd pass but I still didn't get any heat in them as there was no smoke off the rears in the burn out. I launched at about 4k on the 2nd launch and it hopped a couple times then stuck. 1st run I tried slipping it in at 3500 and it was a 2.3 60ft. I know for sure more passes I could have got a 1.8. I didn't bring the lap top to bump the rev limiter, but pushing the rev limiter out to 8500 and more tire pressure in the fronts probably would have got me a better trap speed.

I see the trap speed being kind of disappointing. What's the cars weight? I figured with basically 280 wheel you'd be closer to the 110s

So for TT4 I needed to cut the Avg hp about 20 and I did it accidentally. I changed the intake piping around and air filter after seeing video from the dyno of one of the silicone hoses sucking shut after the vtec cross over. I put it back on the dyno with the redesigned intake pipe and lost 22hp at the wheels (I was dynoing super hot, with the rear tires at hot and sticky and bleed down to the min pressure for the dyno cert form). What I thought was going to be better is either way worse or it needs a retune. Based on my acceleration at sebring and the drag strip I don't think I'm in the high 270's currently. It's going back on the dyno here in a few weeks as I'm making a few more changes (ram air Radiator). But I can only make an avg of 245 for TT4.

I also think Had I bumped the limiter to stay in 4th it would have trapped 104-105. My 1st pass I ran the limiter for a while and trapped the same. That Pass I pulled 5th and trapped the same.

Made some small changes to the intake manifold over the weekend, Also swaped the waterpump setup to a K20 to add a factory oil cooler. Ran into a snafu and it's all apart now waiting on parts. But My Prototype Ram Air Radiator showed up and it fits.

mixwell

that's a clever design. i like it.

f20kills

where is the ram air going? Intake? or is this for more cooling to the rad?

Mrsideways

Intake, I'm going to put a thermal barrier inside the ram to keep the radiator from heating the air up (however that could be used to make it dyno low). The good news is just setting a basic fan infront of the car blow at it I felt pretty significant air coming through that hole, so hoping it will be magnified at 100 mph.

Mrsideways

Ram Air Intake Complete and installed. I foam insulated the inside of the box and with the car at operating temp and the rad fully up to temp just sitting here after 30 mins of running the outside of the box measured 107f and the inside 65f with an ambient of about 55f where it was sitting, I had a small fan placed 10 ft in front of the car as well to try to simulate the dyno. I"m pleased with that.
