Supercharger Kit

-
About 8 years ago they were at the MATS show in Vegas.
They had several cars on display Small Block,RB,B and a Slant.
At the time the kits were around $4000.Very well made.
 
only reason I haven't ordered one already is I want more than 8-10psi boost. would like to get my hands on a procharger kit.

I think 10# on a slant would be plenty. Turbo's will get you more but at what close. You need to think about reliability and the belt driven superchargers are a bit easier to control it seems.
 
results? or a link...not sure if that is a subscription service or not. would love to see results posted here for the rich.
 
For Intercooled ProCharger EFI/TPI applications with compression ratios less than 9.5:1, boost levels of 14-17 psi can be safely run with full timing on pump gas, and will produce horsepower gains of 75-100% (depending upon the boost level and the motor specifications).

For 9.5:1 EFI/TPI applications running without an intercooler, boost levels above 5 psi will require the use of ignition/timing retard on pump gas, and will produce horsepower gains of 35-45%. Boost levels above 12 psi should generally be avoided even with racing fuel on a 9.5:1 motor. Of course, lower compression motors will be able to run more boost, and higher compression motors should run less boost, everything else being equal.

For carbureted motors, the rules are slightly different. Carburetors deliver the vast majority of fuel in a liquid state, and as this raw fuel atomizes from liquid to gas, a chemical state change actually occurs. Due to this endothermic reaction, which draws heat and cools the incoming air, a carbureted motor can safely handle more boost than a comparable EFI/TPI motor. For carbureted engines with compression ratios of 9:1 or less and boost levels in the 8-14 psi range, pump gasoline works very well. Compression ratios of 10:1 and higher require lower boost levels, higher octane fuel, intercooling, or some combination of the above. Compression ratios in the 7or 8:1 range can usually handle 12-20 psi on pump gasoline.

that's a big spend to be limited to 10psi, on a low compression slant I would want to see 14-16psi ( that's just me ) they run more boost than that on the little 4cyl. in the chevy cobalts ( those are 9.5 to 1 motors ) and run much higher boost

4 cylinder engines are actually stronger than a slant 6. They have 5 mains for 4 cylinders. Chevy Ford and AMC 6's have 7 mains and can handle a lot more boost. A slant 6 only has 4 mains for 6 cylinders. THe blocks and cranks must be strong to last as long as they do. I wouldn't push too much boost into one though.
 
So...carbed slant with the TS supercharger as thats what most will run. Post up some results here. 14 posts with no data? I'm really curious as I have a turbo slant and never dynod it.

Don't remember the numbers, but I remember they popped the head gasket.

Looked for a link, but appears you have to be a member of MTOnDemand.

There used to be a turbo /6 Simca that was pushing over 600 hp. And I know there is/was one in Aussie Land that was similar.

Here is a supercharged on that is supposed to be making 600 hp:

The Australian 6's have 7 mains like the Chevy, Ford, and AMC's. I talked to that guy with the Duster but didn't ask him what he runs for a crank or block prep. I will next time I see him at a show.

Wasn't an Aussie 6, but a slant 6 in Australia.
 
That blown Duster 10.56@124. Wow. That an honest 500 to the wheels. How many blocks has the guy windowed?

Looks like it's port injected. Probably a pretty stout engine without the supercharger. I see the Simca is injected on alcohol with 10# if boost. The thing weighs 2300# and it doesn't take a ton of power to run 9.80's. Let me look it up.

Wallace calculator says 475 horse would get you there. I bet the Duster with 600 horse is a stretch.
 
You could take a slant and hang a supercharger or turbo on it and give it 15-20# of boost. But I wouldn't.

Might be right, been a lot of years and I can't find the reference to the guy in Australia with the turbo slant. Thread had people that had ridden in his car, but I don't remember now if or how the "600 HP" comment came about.

Ah, Cameron Tilley, it's referenced in this article - https://www.slantsix.org/ssrn/issues/10thAnnsm.pdf

Found another guy pushing 10's at 127. Here's a video of it making 370 rwhp:

I did find pictures of Cameron Tilley's NA 370 HP slant that (I guess) spun to 7500 RPM and was missing the first and last main caps. Of course, now I can't find the pictures.

Probably a 198 rod motor. Purposely built for sure. Anything can be done. I could probably build a 370 NA 273 and spin it 7500 as well. But why? Just to say I did. You can do that easily with a 360 and the right bolt on parts or a fairly mild 4" stroke 318. I guess my point is, a slant 6 is not the most strong block around especially if you're packing air inside.

I think it was the motor he used in his road race car.

Either way, my only point was that it didn't live at 7500 RPM, but broke the block. Wasn't tossing the number out to say "look what it made", or compare it to anything. Just a label.

I'm not in the /6 game anymore, so I really don't have a dog in hunt here. Just sharing what my (spotty) memory had.
