Road race, Auto X, or the Drag Strip
Mon Jan 18, 2010 2:23 am
Just finished my second race weekend.
1992 GT-4 RC.
GTX Class. Studded.
I will try to post as much as I can about how the car is running. Today did very well. Hope that the car keeps performing the way it is. I'm pushing to the absolute limit. 2nd 3rd gears shifting up there at 7000. touching in fourth for a bit. The club had a radar gun out there and shows top speed around 120 KM/H. I really think we're moving faster than that. There's a Eagle Talon out there that's just insanely quick. He's pushing somewhere in the 325+ HP. There are a couple tuned CRX's out there running real strong, but the AWD keeps me pulling ahead of em.
I'm not having any real issues yet. Just trying to keep the temp down. The air temp today was around 0 degrees c. So around lap 7 or 8 of the 2.75 km track, she was starting to warm up. have flushed all the fluids before the season and am keeping up on the maintenance. Man, the car is awesome. You throw that thing in there deep and it can pull you back out, also if your slow getting in just roll on the throttle, exits quick.
What do you guys think that a good boost pressure to run would be? Got my MBC set to 0.9 Bar, seems fine. Just don't want to cook things cause we got 6 more race weekends.
Got lots to do to the car this summer and all the info is right here. Got some forced induction VERY knowledgeable guys here helping me out, but you guys got the ST185 knowledge. Will be asking questions as I go here. As far as I know the car is damn solid and I am quite impressed with its output.
Thanks for this great resource.

That talon might be faster making more power, buuuut it looks retarded, the alltrac still looks amazing
sounds and looks like you get to have tons of fun.

Tons and tons of fun. Just trying to keep it reliable. Have to change oil and rad fluid this week. Put exhaust back on the car as it fell off. Then repair tires. Lots of work but well worth it. Will post more pics as soon as they hit the internet. Trying to find video as well. The car made a few clips on our local news station.

LOVE the pics dude! esp of the glowing exhaust manifold/exhaust housing!

I like those other shots.
Why do I have to have that heat shield on? I was thinking that i would want to expel all that heat with it off. The only thing that was happening was the throttle cable housing was getting pipping hot. As well the little rubber seal or something around the bonnet vent melted, besides that no other issues. Considering I'm changing oil after every Sunday I also wanted to easier get to the oil filter. Hopefully next weekend will be colder. I'm trying to track down a video camera to get footage in the car. If anyone in thunder bay wants to lend me their video camera we could mount it before Sunday.
I think its sad to turn the car into a ice racer, but got a good deal and wanted something truly capable. I expect to develop the car much more over the next several seasons hopefully campaign it to a couple championships.

Awesome, Thanks for sharing n Goodluck

Awesome, someone else ice racing an alltrac, and in studded class nonetheless!
Love the pics. For the overheating issue just pontificating... you may just need a new radiator and/or a high output fan to assist when vehicle speed is not very high or sideways
Lots of guys run a big aux oil cooler in front of the radiator as well, which can make a HUGE difference in a turbocharged car. Also, an aftermarket downpipe will increase power, reduce underhood temperature AND give better access to the oil filter.
I am planning on doing studded class here next year. I have to aquire/fab a rollbar/door intrusion beam first.
Does your club limit your studded class to using the menard spec tire (as it appears you run)? We have found that homebuilt studded tires (SL=stud limited) can perform as well or better than the menards, for less money. As the menards are supposedly no longer being made and more and more people are having the caps throw off of them, the homebuilt tires will be getting more and more popular. We also have a SU=Stud Unlimited class with no limit to the number or length of studs. These tires shred the ice, but can get grip much better than even that of a race tire on asphalt; insane grip.

Another ice racer. So we did 7 races this year. Won Studded class, and overall (hopefully).
First Issue. Tires. went through eight of em. Menard tires. They didn't hold up. They may be good for the rear tires in some heat races next year. But their not fast anymore.
Besides that i had absolutely no problems. I crashed twice on the same day. the last day. It was warm(slippery) and i had the wrong tire pressure all day. No real damage but some stuff to straighten out. Not to mention she almost caught on fire, from the exhaust breathing on the tunnel, as i hit a snow bank at a 100k with the rear end (trying to save it as i dove in way to hot, and because i was following a 200+ hp CRX, and a 350-400 horse eagle talon. Therefore, zero visibility:)
the car pirouetted. I saw sky for a moment.
Again no problems with the car. The thing is tough.
One day the motor spit up some water. The weather was way to warm. no big deal.
I changed the oil after EVERY weekend. I think the motor is still perfectly sound so I am not taking the head off this year.
over the summer gonna pull the motor, do a clutch and flywheel. Solid mount rear end. Lighten the trunk lid, fuel cell. Loose the ABS. loose the Air Conditioning, exhaust (do up proper) and intake. relocate battery.
This car is super capable, stock, (with boost turned up a little) and we ran away with the whole show. I think I won three or four feature races, and an endurance race (50 min).
I am not trying to get gobs of horsepower from this thing yet, but i am going to lighten the car. I scaled it with half tank. and me in it. 3007 lbs.
59 percent front, 41 percent rear.
51 - 49 crossweight.
Gonna balance the thing out a little more. Also add a wing to nail it down at high speed. I don't care if guys say it does nothing or looks lame. I Know that if you make one the right size and place it properly. They work. 135km. Was our top speed. The track was not built for top speed. Next year, depending on what the club does, it may be something different.
Our club is looking at doing the bolt thing. but it chews track pretty good:(
So we don't know. more than likely menard tires. I used windsheild urethane all year.. on the lugs of the tires. If you could sometimes make the urethane stick good it gives the tire more to wear on. I think it's the only reason i made it all year on eight tires.
currently searching for parts, don't know good from bad on any of them. Any advise on any thing let me know. Ice racing is truly crazy shit. You really find out what your car is made from as it will be at full song for 8 laps in a heat (3 heats in a day). and 10 laps in the feature. That car took everything i threw at it and we worked good together to put it to the front each race. To get where i eventually want the car to be, I think that i am going to pound the pavement and get some local businesses to sponsor the car. As I am in business for myself I believe I can scrounge up a few bucks from friends. I want the championship for a number of years with this platform, and the key is to keep it reliable.
Anyway gotta go. To bed that is.

I agree they are quite the tough car. I crashed a lot during "unofficial" practice, but not during any of the actual races. I was amazed at how well the car took the hits into the banks and sometimes rally style rough track surface with no actual damage to speak of. We had banks from just 6" up to 2" at various points during the season. Sometimes glare ice and sometimes really rough. I did build a front skidguard to help stop snow and ice getting caked under by the prop shaft, and I think something is in order for the rear as well.
I am amazed your car is that light with a cage installed and things such as AC still in place. Mostly just the interior is missing, and lightweight wheels? What else? 260-270hp is relatively easy, and with just 3000lbs that makes for a good ratio. My 165 has yet to undergo any weight reduction.
A guide one of our more inventive members wrote on building the "bolt" tires. Note his winged yellow focus in my ice racing thread.http://www.michiganiceracingassociation ... =tire+tips
The "SL" style tire (less than 1/4") does not chew up the ice that much. It is comparable or maybe slightly more than a menard tire, but nowhere near as bad as a SU tire. You don't have to deal with chunking, or throwing the caps off. You do have to spend a lot of TIME building them. I plan to build a set for next season.
The reason for the SU and SL classes are because we have had such a poor turnout for studded racing. I think the SL tires give many advantages to the Menards. Menards are (IN MY VIEW) expensive, not quite "reliable", limited in size, tall, and going away anyway. They were very decent performers, fairly well designed, but had a lot of drawbacks that limited the stud racing (around here anyway).
