Default so my buddies are trying to talk me into a blower

I have been dead set on a bell s2 kit because it looks complete, and will conservatively get me to 250whp. I plan on running MS.

Gary Shuhart (track dog racing) is my sister's neighbor. Obviously there is a ton of support 20 miles from my home, and I can get an mp62 with an fmic for $2500...which is about 200whp.

Which direction would you go, and why? It seems like they really have to do alot more work to get power down, and aside from Gary's 278whp car, everyone else is only putting down like 210whp at the most. He also has a ton of knowledge on the EMU.

I've done a turbo install on many vw's before, but the kits were always sketchy. I still think the Bell kit is the best idea, but I'm a *****.

I'm tired of going back and forth, so flame away...I understand. If I didn't live out of a suitcase, I would have bought something by now.

I'd go turbo just because of the expandability and I like the power output of a turbo. The linear power produced by superchargers isn't my favorite thing. I like boost when I want it and if I want to stay out of boost that is something I'm capable with my turbo setup.
I say go Bell S2, the only thing i like about the track dog kits is the over the radiator IC setup.

Do the Bell kits typically come together and work without any hitches, and or mechanical adjustments/problems?

Welp 1st off this is a Turbo fourm and Bells kit is pretty bangin' so im guessing most ppl are gana say go Turbo.

If it were me I would go turbo just cuz its way more power and I just love the way a turbo car feels. Goodluck!

they should the mp62 is good platform if you wring it out abit 250whp is doable, but drivetrain stress etc will be alot higher with the SC given more lowend compared to a big turbo. you probably wont get past 300 whp with the 62 though you must cosider thiis aswell. As the fact that a greddy td-04 flows 428 cfm at 15 psi and the 62 flows 440 or so at 10 psi wich seems to be close to the limit of how fast the blower likes to be spun

my older style 1.6 kit went together pretty smoothly, but the blowoff valve fitment was really a pain to fit together. that part of the design has been redesigned since then. Also the new intercooler piping layout is far better.

Do the turbo, something real custom like with a td05. You can probably pick up a 14b for real cheap now. I wouldn't want to do a blower now that I have done the turbo route.

if you had said twin screw / whipple (a la uber style) I might have thought harder about it... but let me put it another way:

the homies on this stoop drink 40s.

and then let me put it one more way from a mechanical engineering standpoint: the turbo takes waste energy (heat) from the car and converts it to mechanical energy and then back into combustion energy with a high theoretical thermodynamic efficiency.

a supercharger takes energy directly from the drivetrain (parasitic loss) and turns it into combustion energy--leaving all that exhaust energy to go to waste.

which is more elegant?

If you're gonna send a check to BEGi, have em do one of those Stage 5 manifolds with the external wastegate. That thing is pure sex. I would it. Only a few hundred $$ more, and the downpipe is sick.



IIRC, it's built for a T3, but I'm sure you could get it flanged for a 2560--wich would definitely get you where you want to go.

Hustler, do you ever make it down to San Antonio?

You should really consider coming down and visiting Corky's shop. If you do get a chance to come down, I'd be more than happy to let you drive my car. I have a 1.6L so I only had really two choices: turbo or JRSC. The JRSC wasn't really an option as it doesn't put down that much hp for $. I'm glad I went turbo.

T3's are the bomb...there's a reason he built the stage five based on a T3 and not the 2560 like the rest of his kits.

Yeah, and you're not biased or anything
IIRC S2 includes a 2554.

I know my voice will be lost in here .... but... 2500 for 62 + TDR is a great price.... Going to add TDR to mine.... to help keep everything cool. Gary's full of info, met him at the Gap a couple of times.....

There's a guy here who has 240ish out of a MP62 + TDR + FM link ... at 12 psi or something like that. Mine non IC'd with only 7psi, is probably doing 170ish (But it hasn't been on the dyno yet). Afterage output is usually in the 190/200/210 range, depending on the model, the header, the fueling options, etc...

I say, drive one. Drive a turbo. You'll either want both, or it will help yourself decide. I wanted the blower. Driven a whole bunch of snails. I like them, still happy with blower. Need to have second car with a snail on it though, so I have one of each. <G>

Dave,

He's right... you need to drive some cars that represent what you are looking at.

I drove one friend's turbo car and hated it. It felt like you flipped a switch at 4k rpm... up to that it felt stock, after that it was holy @#$%! I prefer a more smooth/linear feel, so I'll be going with a smaller turbo or a supercharger if I can find a deal on one. I wouldn't have been able to narrow down what I was looking for if I hadn't driven a couple other people's cars.

I would of course say go with a turbo, but then again I like way too much power and more of the holy sh*t feeling than a linear power adder. Just the way I roll. Do what you think you will enjoy more, as thats what its all about.

I've had both a SC and turbo... you can obviously tell what I have now and there is now way in hell I'm going back.... unless it was for a whipple based (moab) kit and even then its only a small chance.

Install a Turbo and have the Blower in the passenger seat.
Best of both worlds...........
