You got it.

If this is in reference to the silver S2K at this year's UTCC, that was driven by Skip Merriman, who can seriously wheel that sucker around. A lot of that time had to do with his driving talent/aggressiveness. He was also on A6s, which is what any Miata would also have to be on (or something better) to get anywhere close to that time.

In comparison (because I'm a Honda guy) an H1 car that weekend did roughly the same (~2:12-2:14), minus the one driven by Mike Skeen which layed down a 2:10. These were all done on 225 RA1s, ~220-230whp, 2400lbs with driver.

That's fast! ESP. On ra-1's
I'm no Mike skeen. But there's a bunch faster guys out there than me. In comparison, the Guy that won the rwd modified class championship in 2008, 2009, has a 360whp, 2150lb (w/driver), Miata. Usually runs 225/45/15 nt-01 but could run 275/35/15 a6 on 15x9 wheels. Speaking of that, what's the setup wheel wise those h1 guys are running? I know alot of people are running 949 6ul wheels. 15x9's all around? 8" on the rear? Think they would fit on a crx?

I'm not sure about Skip's S2000 (which isn't quite an H1 car anyway), but the other guys are running no wider than 8" wheels. Whitaker's Integra (the white Exedy one) runs 17s I think, and I'm not sure of the width (he's also not on RA1s though; complicated HC political BS).

A 275/9" wheel won't fit without a bit of work on the front, and the rear will need some fender rolling. I have 8" (+40 I think?) 6ULs on my EG Civic, and they fit with a little fender love. The CRX has a bit less room underneath than mine.

I wanted to get in on this event next year, but I don't think funds will be available :(

the 275's were what some people fit under the miata. i was trying to figure out what i could stuff under the crx. i have some 225/45/15 nt-01's and hoosier r6's, need a wheel to put them on crx if possible.

I put 15x8 6UL's on Kireans crx with 205 RA1's and it was hella flush. I think Emilio might have a pic.

stinkycheezmonky

225 R6s are about the limit for a Civic and stock fenders. I have a pic somewhere of them on mine, I'll try to dig it up.

WTF is hella flush? And 205s, especially RA1s, are a little narrow on an 8" wide wheel. I currently have 205 BFG R1s on mine, and they are a teeny bit stretched.

The fast ITA CRX's run 225 Hoosiers on 15x7 wheels. Fast as in 2:17-2:18 on the full course, SCCA ITA that is.

7" wide wheels are the largest you can run by the rules.

stinkycheezmonky

The 7" wheel with a 225 is not quite ideal, though people make it work for given rulesets (just like a 275 on a 6" wide wheel in some autox classes). I've seen a number of Hondas tested with a 225 on an 8" wheel, and that seems to work very well.

fast!

i have to say though, if a h1 car can run that, for sure the fastest miata's will be in the 2:05-07 range.

jacob300zx

Flush as in no more room on a crx. The RA1's were not buldged and not stretched.

Edit: I don't care who you are in Honda land, show some respect or I'll tell your mom you've been misbehaving.

stinkycheezmonky

Maybe we have different opinions on bulged/stretched, because I've seen 225 RA1s on the same wheels. Whatev. Not sure where you're thinking I was "not showing respect" but you are mistaken.

With a similar type driver, yes, I agree. Skeen is a friggin' wizard, especially there. I see a lot of you guys talking about aero limitations on the Miata. Any idea how that compares to aero on a Honda?

Not sure how they compare. I know miatas aren't very slippery. And my car had alot of lift up front above 100mph. At tws I hit about 130mph on the front straight, and the steering got eerily light. Once I put a splitter on it felt planted. Did that just before I went to vir and it helped a ton. I can't really remember how the crx felt. Its been a couple years since the last time I tracked it. I do remember it getting up to speed alot faster than my Miata though. I had a self imposed speed limiter of 135mph, but that had more to do with not having a harness or rollbar than Aero spookiness. There was a high speed kink linking 2 straights at a local track we had. In the crx I would get to 135mph before the kink and just hold that speed through it till the next braking zone. My Miata would only get to 125 or so before the kink, and by the braking zone I would barely reach 130 or so. My Miata was a daily back then though, and it weighed about 300lbs more than the crx with about 20whp less. I'm gonna make a splitter for the crx and some aluminum mounts so I can bolt the wing from my Miata on it.

stinkycheezmonky

My brother's 240SX was similar with the front-end lightness. That is some scary **** for sure. His was most noticeable ~140 on the back straight at VIR, and when you're cresting the hill at that speed and the front does that....YEESH.

Try mounting a splitter at 0* angle and hit the back straight at Road Atlanta! The rear wing lifted the front up and that splitter really lifted the front - freakin scary as hell - like it was floating. I immediately pitted and added down angle - was an increadible difference. The entire car felt planted like a rock at 135 before the braking zone.

the splitter is supposed to be @ 0*. it's not there to make downforce the way a wing does. it's creating "net" downforce, which means it is reducing lift, thereby creating the same as downforce. angled down it creates more drag than -lift or "net" downforce. miata's have alot of inherent lift up front, lowering the car, installing an air dam and/or splitter address that issue.

Honestly, the first time out it was "eye-balled" - never put an anlge finder on it, so it may have have been pos up angle. So can you be sure it doesn't go positive (set at 0*) with rear wing down force? Just sayin' - adding 1.5* neg angle greatly improved the front handling in the back straight. Not meaning to get off topic.

Mine doesn't. I have pics of my car at 130mph. But then I also have coilovers so it has 360# springs in the back, run a little rake (1/4" higher in rear) and don't run a full tank of gas on the track. It would take a ridiculous wing to what your claiming.

I would love to see a reliable and fully built miata at this event. The past few years, while I've been reading about it, some seriously bad *** vehicles were the winners.

LOL at the new uber varsity cars. Ha ha F1 cars.

FWIW my car is getting tuned on Tuesday by Phil Grabow who placed 19th in the unlimited class this year with a time of 2:06.8

I will try to remember to ask his opinion of the event.

stinkycheezmonky

FWIW, as fast as the uber varsity cars are, they are still 10-15sec/lap off the F1 (vintage F1 at that) record pace.
