Tracking with Forced Induction

[kcam86]

My question is how much difference do turbo blankets, ceramic thermal coating and thermal wraps make? Ty in advance

Can you explain to me how an oil cooled Rotrex supercharger with a heat exchanger and intercooler along with added pulleys and belt complexity has less parts that can fail?

Since when do superchargers not have exhaust manifolds/headers as well. In fact many of them add additional pipe in a similar area to most turbo kits. Regardless of the forced induction kit, heat has to be dealt with.

Yes.

I'm saying turbos have to deal with BOTH, whereas superchargers do not.

When you're cooking on your stove, and you can "feel" the heat when you get close, that is radiant heat. When you keep your hand in that spot where you feel the radiant heat, and it starts to burn, that's heat soak.

If you reduce the number of items (and thus, surface area) of the sources of radiant heat, you reduce heat soak.

SC: header

Turbo: turbo manifold/header, turbo, exhaust/dump piping, turbo itself.

The supercharger is compressing air and is being oil cooled no different than a turbo, it is just being spun by a belt instead of the exhaust gasses. It has to be factored into the heat equation.

An actual track car running the Full Blown kit made that recommendation as it eliminated their overheating issues at the track.

Then you're wrong. It's already been done (not on my car, but another 86 with similar exhaust mods). I may not make 200 exactly on a Mustang, but it will most likely be 190-200.

So, no bubble to burst. The 200whp wall on pump gas & NA has already been breached.

On phone I am. Therefore, if mistakes I make, Frank Oz blame you should.

I have a lightweight tow hitch so I can put a small tire trailer on my car and tow. When I went to VIR, I just used a UHaul sport trailer and borrowed a bunch of jugs and filled with E85. A little bit of a hassle but it works for me.

Ya totally agreed E85 makes sense for tracking, i hv done calculation given E85 also burn 15-20% faster than 100 Octane, i will need total of 30 gallons per track day for me..... I hv a rear diffuser not able to add tow hitch....

You keep saying it's been done, but you aren't providing any proof. I'd like to see these magical 200whp, NA, 91 pump Mustang unicorn dyno graphs you are talking about.

On a dynojet I believe someone did 200whp. I have yet to see someone do 200whp on a mustang dyno.

Sorry to burst your bubble as well!

Running SC or turbo doesn't matter. Just keep an eye on your water temperAture and oil temperatures. I think for water, do not exceed 110'c and for oil temp 130'c (track levels). Please correct me if I am wrong.

[Tye300]

Dyno numbers are subjective anyway. Showing the baseline is more important before breaching the 200whp mark. When I was NA, I baselined 135whp on a dynojet. After tune, with headers and exhaust, I was around the 160whp mark. Imagine if I baselined 135 and hit 200whp with exhaust mods on pump gas, now that's a unicorn in the flesh right there!

OT - but some data on oil temps:

Take it for what it is but I saw a post somewhere with the wiper plastic being removed and it caused a negative pressure pocket right at the windshield that forced are into the engine bay. Not saying this good or bad but maybe you guys can relate on the pros and cons of it. Since both of you are pretty knowledgeable in many regards to this car. ty

It's called a search feature.

Edit (now that I'm on a desktop instead of on Tapatalk's limited platform): I apologize for the above. I finally found the chart, but it took a) knowing it definitely existed, and b) searching for the "thanked" posts of the tuner (b/c "posts by user" maxed out before the posting date of this post). So, it would have been incredibly difficult to find. It was effectively buried in the forum.

The 200 whp on E85 you're referring to was done by Shiv on a dynojet (iirc. may have been a mustang), and it was 207 rwhp. Here is the post with 200 whp on a mustang dyno on 91 octane pump gas in AZ.
