What makes more power?

The kits are very close in price, what is better bang for your buck?

What would bring more power if the motor were built to a 383 with compression around 8.5:1?

 

your second link doesnt work?

Superchargers are much more common, readily available. Turbochargers will make more power since it's not belt driven. you size the supercharger or the turbocharger to the engine size. So, a 383 "should" make more pwoer than a 350. But don't let displacment concern you. Look up thread by lcvette, Chris has build a turbo 355 that put down just short of 1000rwhp...

always a few questions involved...

how much power do you want?

how much money do you have? lol...

You can go B@lls to the wall with a supercharger as well, and install a YSi vortech head unit or one of the many offered by Procharger (equivalent size) and also make something like 650-800+rwhp.

this is a very general response. they both "behave" differently and the end result is usually the opinion of the owner (which one is "better than the other").

in my opinion a positive displacement supercharger (i.e. TVS 2300 eaton, Whipple 140ax/175ax, kenne bell 2.6L-2.8L, etc) would be the "most fun" combination... one "minor" detail is that no-one makes a kit for the superchargers listed... and hood clearance, room for belt drive etc.

 

Ok 650-800rwhp is waaaaaay to much lol.

I'm looking for about 500 hp & tq, I could probably accomplish this with the 350 right?

I don't have a lot of money, (this will take place in the next 3-99 years).

 

Does it matter that I have an 85? because of the flat-top pistons, and iron heads with the 76cc chambers?

Or will the company be able to calculate the right amount of boost for my application without me having to change heads/pistons or something?

 

if you've got an 85' I believe the only vendors that make a kit for your car are Greg Carrol (blowerworks) or Procharger. I recently visited vortech's website, and it looks like they discontinued their kit for the c4's.... (at least the LT1 platform).

greg would be the right person to talk to.

Your horsepower goal should be easy to reach, although will need a built bottom-end.

 

 

Always make more power with the turbo - but - that's not the real question. My supercharger kit is perfect for you !!!!

BR - greg@blowerworks.net

 

what does BR mean?

I think I requested a catalog, I'm not sure lol.

 

Greg- great of you to stop in dude!

Chris

 

You have TRW forged pistons in your engine already.
if it is stock.

 

Yeah its all stock, forged pistons are good for boost right?

 

BR = Best regards !!! LOL

 

I was thinking supercharger on my 94 in the future,but the turbo kit looks like a better choice.The horsepower numbers are pretty sick.Thanks for pointing that turbo kit out.

 

Yep ! Your exaust is the only draw back to your car.

Change the cam and heads and a good intake and you are good to go.

 

since it will require a rebuild, you maybe better off buying a stroker shortblock, say a 410 to 420 smallblock and could achieve that power NA with some good heads....... I do understand the lure of turbocharged power though, but it maybe cheaper if you just want the power level.

 

it would be cheaper to turbo or smallblock?

Supercharging i think would be the way to go, because one of those kits for turbo'ing has to take like 5 weeks to build they said. I'm pretty sure the supercharging kits would be readily available.

Vortech or procharger though?

 

just to let you guys know the turbo kit is bogus. There is literally 1 guy that we (the forum members) know of that ran that turbo kit. It was junk. Tons of trouble with the kit. Go ahead and ask around man, NO ONE has any experience with the turbo kit from HP performance. There have been a handful of threads on here about that exact kit.

the only "kit" would be the raptor/STS kit, but that thing is still in the works and they are having trouble getting it through emissions etc.

WORD OF ADVICE FROM SOMEONE WITH FI EXPERIENCE: buy your kit from Greg (blowerworks.net), i am telling you now that you will save yourself A TON of hassle with trying to "correct, clean up, or fix" the standard procharger or vortech kits! Believe me!

Turbochargers are a lot of fun, if you can source some callaway stuff, i would say go for it! otherwise, you are going to be "pioneering" your own kit. Sure there is a lot of support here, but the end result is A LOT of down time, A LOT more expense (learning curve, development etc).

If you want to purchase a rock solid kit that will get you what you're looking for, buy from Greg.

 

BTW, how many times do you see the vendor here posting and responding to threads? I had a nightmare of a time trying to get technical information from vortech directly (regarding my kit). The support was simply not sufficient.

you've got the luxury of a quality vendor willing to spend time with you on figuring out any questions that you might have.

having owned three supercharged cars in total, i can tell you that NONE of them would have been successful without the proper support/supplier.

 

So blowerworks is what i'm after..what's better vortech or procharger?

are there any kits that would allow the use of the air conditioning? I can't live without it especially right now, its gonna be 90+ for the next week..

 

Pwnage1337-

Greg's kits are complete and they allow the retension of A/C (believe me, I know hot- I am an AZ resident).

He primarily uses Vortech "head units" (superchargers) for his kit, but i do believe he can offer you a procharger kit (if you prefer).

There is a lot of debate between "which one is better". Honestly, it comes down to you. the procharger head unit is "self contained", which means you don't have to find an oil feed source or a drain source (i.e. drilling into your oil pan). The Vortech uses the engine's oil supply to keep the internals lubricated. Everyone is going to have their own opinion as far as "which one is better", but it seems as though the dedicated racers prefer using the oil supply from the engine to keep a constant supply of oil to the supercharger. And you get to change out the oil every time you change your engine oil. it's going to be much tougher to change out the oil in the procharger (relatively speaking of course), as well as the fact that the procharger will require a special type of oil.

On the other hand, all superchargers have a "transmission", it's basically the internal drive arrangement that allows the impeller to spin at a certain speed in relation to how fact the engine is spinning (RPM). the Procharger head units come with a 4.10:1 transmission (at least the P1-SC, which would be the head unit of choice for you), which is relatively short, and does a good job on a low RPM engine- street use. The vortech head units vary in the "ratio" available (Greg will be much more accurate with this info than I am), but NO vortech head unit (at least not one that will fit under the hood) have "as short" a gear than the prochargers (i.e. the vortechs seem to be in the 3.20:1-3.80:1 range- not quote me on that). This is a minor detail as the pulley combination that you choose will also drastically weigh the outcome of the superchargers behavior.

the "T-trim" V2 head unit from Vortech seems to be relatively popular here on the forum and with guys looking to produce anywhere from 400+rwhp (stock bottom end), up to as much as 650+rwhp on a built 383. The smaller head unit "S-trim" v1 or v2 will not support the big HP numbers. the step above that would be the V7 YSI (I've heard it's a tight fit with the vortech bracket, but should be just fine with Greg's bracket).
