Looking for 700+ horse power

[juiceball44]

can't you supercharge and turbo a car at the same time?

ya you CAN do it but its just an unnecessary hassle, if it was worth it don't you think full drag cars would do it....

[tinyguy2]

running a suppercharger and turbo would eliminate turbo lag.

[G-1000]

so would a good wastgate or twin turbo. Turbo lag is only from a poor set up.

This nice thing about a turbo is you can build max boot right off the bat. A supercharger is lehner so you need to trun the rpm for max boost.

That only applies to centrifugal blowers. Roots type make their boost at idle.

still lehner.

[T3/T4 GSR]

Yea but you said you need to spin the motor to higher RPMs for max boost which isn't true in a roots blower because no matter what RPM it makes the same amount of boost.

[VWbug66]

just put the magnacharger on that bitch and u dont need nuthin else...that will be the "ass-kicker"

[Jon0489]

hook that bad boy up with a turbo and msd and make it chug fuel

[odix]

whats such a pain in the ass turbo and supercharging a car? a twin turbo'd supercharged trans am would haul ass...my buddies got a ****ing blazer that puts out 700+hp rwhp, l7 or l5 corvette engine or some shit and all these modes

Why because the tunning and just the intake set up would be a giant pain. And really it is a waste

How do you figure. I'm not into roots still blowers myself. My friend runs an 8-71 and I've been in the car. I don't remember it being at full boost at any rpm

[T3/T4 GSR]

Any of the roots type blowers I have seen have always made their boost at idle. I have never seen a non centrifugal blower doing over 10psi so maybe higher boost ones require some revs to make boost but I don't think so. I have mostly dealt with turbo honda motors since most people don't waste their time on blowers for hondas.

What kind of intercooler are you using? There are alot of great water to air intercoolers for F-bodies available. If you want to stick with a air-air cooler, then run a CO2 or N2O cooled air-air intercooler.

I've found that GM motors respond extreamly well to alky injection.

With swapping the pulley (which would raise the boost psi), and adding a proper sized cam, heads, intake mani, and headers you should be able to reach that number.

Personally I'd go with a 383 strocker crank or swap the motor to a LS6 (not that the LS1 is a bad motor, I just have had much better luck building the LS6's)

[TAPPER]

OMG, so much misinformation.

First, a magnacharger is not intrinsically any “better” than a powercharger. In fact, a centrifugal blower (powercharger) is much more efficient than a roots style (magnacharger) blower so all else being equal the centrifugal would be “better”.

Second, a roots blower does not make the same amount of boost regardless of RPM. A roots blower is basically an air mover and works by pushing more air into the engine than it can ingest otherwise, creating pressure (boost). Because the blower is crank driven the higher the RPM the greater the volume of air, hence, increased boost across the RPM range.

Third, turbo’s do not make max boost at idle and there will always be some lag involved. Exhaust gas drives the turbine which in turn drives the compressor. If there is minimal exhaust, like in an idle situation, there is minimal boost. Likewise, there is always going to be a time deficit (lag) between mashing the gas pedal and having enough exhaust to spool the turbo to create boost. Granted, well engineered systems greatly reduce the lag time but it can’t be totally eliminated. (unless you used an external force to pre-spool the turbo until the exhaust had a chance to catch up)

Lastly, whatever forced induction method you use there is a point of diminishing returns. In other words, you have compressed the piss out of the air/fuel mixture so much that the byproduct –heat- is more detrimental to performance than the benefits of the added boost. So even though someone may be able to supercharge and turbocharge an engine the resultant would not be a sum of the components.

MuscleScience, you made a good choice with the procharger. It’s basically a belt driven turbo and offers a nice performance and functionality balance between roots style blowers and turbochargers. Personally, I wouldn’t tear into the engine unless it was necessary or all other speed options were exhausted. Like others have mentioned, a pulley swap and/or finding a way to control heat (intercooler, injection, etc) would be the first choices for squeaking out a few more ponies. If you’re determined to tear into it I would go as big as possible with good quality components.

[MFT81]

how the fck do you guys have enough room in your brain to know this crap and everything in the steroid Q/A forum.......

[tinyguy2]

get one of those tornado things on infomericals they make a million hp. jk. the reason i said supecharger and turbo is cause he already has a supercharger.

[Saunacrank]

I like car discussions.... I actually understand the science behind it all. Maybe if I'd been reading about steroids since I was a child I'd be highly educated on them also though

dang man you know your shit, you said all the things I wanted to say except I didnt want to write it all out.

I was only thinking about tearing into the engine because I enjoy working on my car and Im at about the maximum level of power that the internals can handle (Pistons, rods, wristpin, ect) The stock crank will hold over a 1000hp so I though about keeping stock cid and running forged internals. However I have been kicking around a stroker kit as large as 408CID. I am not sure that I will actually do any of this I just started my doctoral studies so I have no real time right now to work on my car.

Thanks for the feedback.

you guys ever heard of the BATTERY driven turbos? like the one @ boosthead.com .. does this shit work..I wonder how high you can turn the boost up..it takes no power from your exhaust like a turbo or supercharger from the belt.

[TAPPER]

^^The weight of the batteries necessary to drive the turbo negates any performance benefits from the boost provided.

[odix]

not really, it weighs less than a big turbo.. 17lbs total with battery.

[TAPPER]

The website says the centrifugal weighs 17 lbs with no mention of brackets, plumbing, hardware, etc AND suggest two regular car batteries for the average user. A moderately sized car battery is roughly 40lbs so when its all said and done this entire system is over 100lbs.

You can never get more energy out of a system than you put in. The idea of this slick electric unit that puts out real power yet runs off a tiny, lightweight battery just doesn't fly in theory or in the real world. Sorry.

[cold1]

Just buy a diesel, throw a wicked tune in it, some fuel mods, and maybe a bigger turbo. 700hp on the ground and 1300-1400 ft/lbs of torque.

[G-1000]

And propain injection.

[LatinoPR]

can't you supercharge and turbo a car at the same time?

No...is 2 diferent kind of induction systems,or one or the other.






LPR.

[odix]

naa, you can dual turbo, split the intake. one connected to the shaft, the other the exhaust.

[G-1000]

Yes you can run a turbo and supercharge at this same time. It makes for a kick ass set up. The down fsall is it.s very had to do and to much shit going on at one time.

Oh and there a pain in the ass to tune.

[cold1]

Nothing beats a 7,000# truck hookin' up in 4x4 rolling black smoke, and running the 1/4 in mid 12's.

I like those GMC Cyclones, saw one tonight at a local car show. All wheel drive and can be made into an nasty ass street machine. A swedish guy actually has one running in the 8's thats pretty fast for a truck.
