A typical turbo setup will have issues on a road course. Auto X is fine.
And for power mods, I've really debated a TVS supercharger. I'm sure it would offer me the most smiles. I would just be worried about the addition of heat on the track. And down here in Texas, we really have to take that into consideration. I am aware of the VMP/Afco upgraded heat exchangers. That in combination with the 85mm (no smaller) pulley and a conservative tune could maybe alleviate the issue. I just don't have any legit empirical evidence to confirm or disprove that.
Do you have E85 close to you? That would help with the cooling issues you'd have with the TVS.
For track work I would consider going N/A. You mentioned heat, but you also have to consider the higher center of gravity as well as F/R weight distribution. Long term my goals would be a completely forged rotating assembly, Boss heads with valves, etc and a Cobra Jet IM, TB and intake, with full exhaust, and help things out with a light weight flywheel and driveshaft.
Curious on how you figure? Some of the fastest cars on a road coarse are turbo'd lol.
What spring rate are you guys liking on your Koni's for handling? 230-240 front/ 200 rear?
Good points on weight distribution. I hadn't really considered that, but it's a valid addition.
The part that bothers me about n/a is "bang for buck". It seems that I would have similar money as a supercharger invested but only be around 450-470whp. I'm sure that it would be a blast, and the setup would be more durable... But I'd always wonder what another 100whp felt like
if I was using this dampers I would go with 1 of 3 spring selections:
Steeda sports - 200f 175r linear
Maximum Motorsports - 320/360f 260/380r progressive
BMR handling springs - 240f 200r linear front/dual rate rear
these springs are usually paired with those dampers in packages from various vendors like strano, MM and BMR and Steeda have similar spring rates where as MM has a higher rate but they are more experienced with pairing their spring with the right dampers so I trust their judgement.
