tar6day Posted November 17, 2012 Posted November 17, 2012 Is a water spray on the radiator and intercooler legal in ST2 class? Quote
Aaron B Posted November 17, 2012 Posted November 17, 2012 I'm thinking spraying water on your radiator or intercooler is probably not going to go over very well with the cars behind you, I think they outlawed this along with the James Bond oil squirters out the back Quote

Aaron B Posted November 17, 2012 Posted November 17, 2012 Yes! This is why I switched to ST2 and installed bullet proof glass to defend against Ken Smith's headlight mounted guns Quote
Aaron B Posted November 17, 2012 Posted November 17, 2012 Tar6day, Just poking fun, I actually do not remember ever reading anything in the ST Rules or GCR..125 pages that specifically prohibits a cooling spray on radiator/intercooler? It does not seem like a great idea for the potential for water to get on the track if the sprayer stuck on or something like that? The Euro semi truck series run water spray units on the front brakes, when they hit the brakes you'd see a huge blow off of steam, maybe the same would happen with the intercooler/radiator sprayer?

David Fazzino Posted November 18, 2012 Posted November 18, 2012 Like the early Evolution 8 models that had intercooler spray. They worked best with windshield washer fluid for better cooling over water. The spray was vaporized by the heat. No issue with water on the track.... Quote
kbrew8991 Posted November 19, 2012 Posted November 19, 2012 from the TT/PT area I would suspect that the stance will likely be along these lines 15) Non-BTM or modified intercooler +4 (Intercooler sprayers are not permitted unless theycame on the OEM base trim model of the vehicle). However, it isn't really addressed in the ST rules that I've been able to spot. Quote

Falcon Posted December 12, 2012 Posted December 12, 2012 Could you carry enough water to make a temperature difference by spraying the radiator on a hot day? It would evaporate so quickly, I can't see it'd be worth the engineering effort or the weight penalty of carrying the water. Quote

Is that true? Quote
drivinhardz06 Posted December 12, 2012 Posted December 12, 2012 James Bond oil squirters out the back Apparently oil squirtters are standard equipment on AI Mustangs. It wouldn't be funny if it weren't true. Was it the June race this past year at RA? They finally threw the checker when the # of dead trackside stangs outnumbered the flatbeds/towtrucks Quote

I know of one GD Mustang that spilled Exxon Valdese amounts of oil during the parade lap on the straight and in Turn 6 at Road Atlanta for the Saturday Thunder race. That was a f*=king mess. Quote

National Staff Greg G. Posted December 13, 2012 National Staff Posted December 13, 2012 Sprayers are not mentioned in the ST Rules. However, they could fall under this: From the start of qualifying through the end of post-race inspection, vehicles may not have any adjustments or modifications made to systems that could alter chassis dynamometer readings by changing horsepower levels (without the direct approval of the Race Director.) From a practical standpoint, I would say that they are not permitted. They potentially increase HP levels while on the track, with gains that will not be seen/replicated on Dyno testing (unless we test in a wind tunnel, or use an industrial wind machine to get 100+ mph winds). If the entire premise of the series is that we attempt to equalize cars using Dyno results, then it doesn't make much sense to allow a modification that not everyone can use (intercooler sprayers), that can change HP levels and not show on the Dyno. "Ram air" is not exactly the same thing, but is analogous, although most cars can use it. No, I don't want to argue how the turbo cars can't use ram air, so they should be able to use sprayers instead. From a rules perspective, it would seem that based on the above rule, they would not be legal as well. If one were to Dyno the car w/o the sprayers (at full function with 100+ mph winds), but then use them on the track, HP levels would be altered. This could be proven on the Dyno by testing w/o the sprayers, and then getting the biggest fan available and test with the sprayers. If there was even a 1 whp difference then this rule would be violated. Quote

That was a f*=king mess. i am still wondering why they went green after that. even if they felt like the choice was between cleaning up the oil or running the race, had they just ran one more lap under yellow, EVERYONE would have known the oil was there and avoided it. instead of wrecking you and nearly half the rest of the field.

Balroks Posted December 17, 2012 Posted December 17, 2012 I wouldn't risk it, the only time we've ever sprayed the cooler is during dyno days because it's like 150 deg in the dyno room and it really doesn't make a bit of difference. Like others said it won't go where you want it, it'll evaporate too quick in the airflow, and it's just extra weight. I'd put the extra weight towards an uber efficient cooler. Quote
