Supercharger Engine Mods?

walruspuncher · July 22nd, 2009, 12:00 AM

So I've been looking around and finally decided to supercharge my stock 09 Bullitt. Before I do, I was wondering, if I leave the engine otherwise stock, what's the maximum safe horsepower I can generate without any serious engine upgrades and while maintaining reliability?

Also, would you recommend possibly going with a twin?

You can get up to 500 safely but its all in the tune. Alot of people like to be around the 450 area.

navyman8903 · July 22nd, 2009, 12:12 AM

depends on the supercharger. If you are going centri then you can hit the 480-500rwhp mark. If you have a Twinscrew, then you are looking at about 480rwhp MAX. The torque will break the rods before the topend horse power fries the rings......And JOIN THE BULLITT CREW MAN!!!!!!!!!!!

Roush R2300 TVS. It's a gamble any time you supercharge a car. Don't think you can get away with anything. ~450 rwhp seems like a good number if you've got a good tuner. There have been guys that have blown up motors with less power. There have been guys with much more power that have motors last for years. Personally, I think the amount of boost and the tune should be the focus point on making it last to some degree.

450-500 depending on the type of blower and tune.

We have several s197's running our Hurricane Cat 5 kits pushing 480+ on the stock bottom end.

One you start pushing beyond 450-480 you will need to think about upgrading the shortblock.

Almost everyone will say 450 is safe and 450-500 *may* be safe with a proper tune...and I am talking RWHP SAE.

There are many good supercharger choices.

You need to decide what kind of driving you are going to do...street, drag racing, etc.

If you will drag you can go with a centrifugal and save some money; if it is a street car then a twinscrew or roots are both fine.

Choices to consider:

Kenne Bell Twinscrew
Whipple Twinscrew
Roush TVS2300 (Roots)
TechCo Reverse revolution TwinScrew
Edelbrock TVS (Roots)
And there are others...
Saleen
Vortech
and many others.

Personally? I have an older Eaton M90 (Roushcharger) but it is too small and I want more.

I am leaning toward either Kenne Bell or TechCo twin-screws...just need to do some more research to decide. I have one of the top Kenne Bell tuners in the USA 15 minutes away from me so that weighs heavily on my decision (Modular Power House). Eventually I will forge my internals and stroke (Livernois) so I am looking down the road.

Too much effort. Supercharge and be done with it. Bolt ons...geez, you'd be stroking and adding cams and heads and long-tube headers and exhaust and cold air intake and all sorts of crap...lots of time, parts, money...and I still don't know if you would make that number...others will chime in and turn this into another N/A vs. supercharger train-wreck...

A little M90 like I have can make 400 RWHP and takes a day and a half to install (some can do it in less than a day). Bam...done. Used ones are around 3200.

You cant go by SAE corrected numbers. A guy in colorado at 3000 feet making 450hp is gonna put less stress on the engine then a guy makin 450hp on the coast at almost sea level. The correction makes up for the less dense air at altitude. basically it says if your at sea level you will make 450 hp thing is at 3000 feet its not that its less 425 or maybe 390? I dunno what the correction factor is but its somethin you need to think about.

Dimora a TVS isn't a Roots, it's a TVS.

Honestly... the best FI statement made in a while

FI, even with stock engine, take into account drivetrain and suspension upgrades to harness and get the power to the pavement.

walruspuncher · July 24th, 2009, 09:32 PM

I'm not going to be doing much drag racing, except for the odd trip with friends maybe, but that could change depending on if I like it.

Most likely I'll be going up to Pocono every once in a while and drive around there. So it'll be mainly street, but I do a lot of highway driving/open road kinda stuff.

Would the Roush TVS2300 be a good choice? There's a guy kind of nearby who can install it and so I'm thinking of going there. They do a lot of stuff and are pretty well respected. Anyone been there that can give feedback?

scramblr · July 25th, 2009, 03:46 AM

It depends on the motor as well. Our motors are a crap shoot over 450rwhp. I spun a bearing and was running between 450-470rwhp and an excellent tune. The bearing had probably spun a few weeks earlier as the PCM was giving me a Low Oil Pressure warning. The went racing and that finished it off.

Point being that when going f/i with the stock motor, you need to be ready to replace it. Might not be right away, but be prepared nonetheless.

Ahhhhhhhhhhhhh....just do things right the first time.....and go turbo

Naw, it's a roots. Just an evolution of the roots:

TVS Roots-Type Superchargers

Key points:

Four lobes instead of three like previous Eaton roots designs featured.
160 degree rotor twist. The old roots (ie M90) had a 60 degree twist.

So the bottom line is it is a roots blower with one extra lobe and more twist.

You try and correct more statements about F/I than anyone else I know and you dont even have it
