They had that chevy in Hot Rod a while back. Basically the guy was looking at the viability of doing multiple turbos (more than two) on his engine, but most of the shops told him they wouldn't do it. Then he sees these tiny little 1.0L diesel turbos at a show and decides to go all out. Finds...

Upgraded CT 60-1 K&N Intake Full 3" exhaust (no cats) Lex Afm and Denso 550's ~15 psi with 11-11.5 afr Running 275 Nitto DR's at 25psi (No real burnout, just a quick tire clean, as I was using a stock clutch) 12.7 @ 109.5

Yeah, with a 2.5 60' that makes sense, that puts you right in line with my run if you pulled a 2.25. I say keep on boostin, one of these times you are bound to hook up, that is what I had to do when I started out. Do you think you could be pulling a one wheel peel or is your diff in order?

Do you mean into 14's or out of 14's. I ran a 13.8 with a 2.15 60' and 99.5mph, so there is no reason why you shouldn't be mid to low 14's as it is. Do you have a slip? edit: Here is a slip that is closer to your numbers. Even with your 60' you should have 14's easily unless you are...

The other possibility is that they are using electronically assisted turbos. I thought I read somewhere about the attempt of having electric motors spool the turbo and have the engine do the rest. (This information is at least a year and a half old, so who knows what they are up to now.)

It uses coolant but runs on a seperate system than your radiator. It has its own heat exchanger and the fluid is kept much cooler than your main cooling system.

I don't think it is much of an issue to be boosting all of the time (if that is truly the way it is supposed to be, and not a malfunction). With diesel, you usually have a large displacement with a turbo that is designed to make high boost. When you think about the fact that they don't rev...

If you'll check back to my first post, I linked a calculator that allows you to input vehicle weight (w/ driver) and your desired e.t. to get a horsepower estimate. You get the same numbers either way.

5sp or auto? The only low 10 sec mkiii's I know of are 5sp with around 800whp. I'm sure you could do it with less, but it all depends on how much weight you can pull out, and how well you can drive. I couldn't tell you for an auto, but I'm sure there are alot of variables there too...

The reason the HP numbers were so low is because the engines didn't rev. The torque numbers are similar to today's because the torque is still there on the low end, they just make more power now because they breath up top.

NOx is used to refer to all oxides of nitrogen in emmisions, there are numerous combinations. NOx emissions rise with high combustion temperatures, and since the egr is used to help reduce those temperatures, there's a good chance that it is the problem. edit: Looks like I post too slow.

Great video, can't wait for the new version.

If you've seen 25 psi on 10:1, then I don't understand why you needed to ask the question. If you're bothered by the non serious talk then you should have given more serious information, besides your question was answered by a few people already. The issue is, as it is with everyone else who...

I'm curious where you got the 30% from? I've heard about 10-15% drop in most FFV's. If it is indeed closer to 30% that is a blow, but I agree with your thoughts that there is no sense in switching if you don't have enough supply around you, what happens if you have to go on a road trip or...

A few things, yes it is higher octane and burns cooler, both good things for horsepower. The thing about it running rich is true because stoich on ethanol is different than that for gasoline. Your fuel economy will take a hit, but can be minimized with proper tuning. I guess the bare minimum...

It has to do with the efficiency of the compressor wheel. The turbo is like an air pump. We'll make the analogy that we have one pump that is twice as big as another. Theoretically speaking you can move twice the air with the larger pump rotating at the same rate (that is not actually...

Probably has to do with efficiency and temperature. Dual 78s can provide the up to 50psi of boost alot cooler than a single. Those top speed runs last alot longer than a normal drag race so keeping the heat down is really important to engine survival. Just my guess. Yeah, it was a...

That manifold looks crazy, great work. That looks like one of those 1000 piece 3D puzzles. I'm almost glad I don't have access to a welder, or any skill after looking at that. Again, props for your patience and dedication to the project, I can't wait to see it pushing 4 digit numbers. :bigthumb:

If you have 342hp at the wheels, then you are right on par with a new vette. Your car is heavier, but once you're moving that starts to mean alot less. Looks like he underestimated you and lost, nice kill.

My bad, I just ASSumed because that is where your chart topped out. Either way I like the way it looks, 75mph at under 3k rpm.
