Check out my friends Z28. He put in a 6.2 liter engine. Same engine that comes in an Escalade. Its been bored out and is 418c.i. He also installed a 82mm Turbo. This link is a vid on the dino. They are tuning it. He hasn't been able to enjoy it yet. He will be taking it to the strip before long and we will see what it can do. Look under the hood everything is new.

wow. i love forced induction. =P~

i am already looking for an excuse to build a forged bottom end, and add a supercharger on my Z06, and it only has 1100 miles on it. :oops:

that sounded MEAN. what kind of RWHP/RWTQ numbers did it put down?

That must have been a blast to build. Sounds SWEEEEEET

That is a nice ride man.

No numbers yet. Still tuning it correctly. In the vid he has the turbo turned down as low as it will go, untill they get everything right. The turbo is barely doing anything right now, but you can sill here it boosting like hell.

After we get to that point and turn the turbo up, we will see the numbers.

If I had to guess the HP numbers right now, I would say between 600-650 at the wheels at 7-9psi. Of course, I don't really know much about built Chevy's as I am a ford guy but those are the numbers I am going with.

I wonder if the car is too light for an engine that size? I don't know crap about cars but I have floored a juiced up corvette and ended up facing the opposite direction I was going. Just curious.

Throttle management, dude. It's all a matter of timing.

My pants almost ripped off of my body at the sound of that engine. LOL.

you never can be too light, nor can you ever have too much horsepower. you can however, learn too drive well enough to keep it between the ditches.

[gear head nerd]
just some random info on weight and horsepower... weight is important, because 1) it takes less power to move a lighter load 2) weight also plays a big role in cornering and handling 3) when you have a high torque/HP engine, lighter cars will have less stress on drive line components(transmision, clutch, differential, axels, etc) as it is less stressful on the parts to get the weight moving. breaking parts is bad. and costly.

which brings you to the weight to hp ratio. its obviously easier for a 1 hp engine to move five pounds than it would be to move 10 pounds, so the five lb load would in turn be quicker. i believe those fourth generation camaros weigh about 3700 lbs. this one will probably have about 750 hp, which gives it a weight to hp ratio of 4.9 lbs per hp. i think the new mustang shelby comes in at around 3900 lbs. with 500 hp, and a ratio of 7.8 lbs per hp. my vette Z06 weighs 3100 lbs. @ 505 hp and a 6.1 lb per hp ratio. this is with BHP numbers (horsepower at the crankshaft on the engine, without any loss from driveline components). with driveline components in play, it is more accurate to compare RWHP(rear wheel horsepower, that actual power the car is putting to the pavement) number when using this method.

BnGhog, RPM is only a few miles away from where i'm at. i've heard good things about those guys. i plan to go up to raleigh and check em out. i really want to get some headers installed on my car.

That has been the mantra of Carrol Shelby since the time when the first Cobra ever came down out of the chicken barn.

HOWEVER, there is far more wisdom in that post by "gear head nerd" than meets the uninitiated eye. A tremendous engine, does not necessarily a great car make. If the rest of the car is not tuned-up to handle that power and weight (not only weight but -weight distribution-), it is nothing but a nice sounding toy machine or a nice place to end your life in an accident.

I would rather have a 50/50 weight distribution car with a great chassis, precise steering, four caliper Brembo brakes, a well tuned suspension, and a light car with around 300 hp in a real highway situation with turns and straight segments than a quasi-dragster.

In other words, around a complex track with a combination of turns and straight segments, I would prefer to drive a juiced up Elise or a juiced up Porsche Cayman S than that Z28, which will go much faster and with greater acceleration as long as it goes in a straight line. How about that for a friendly offseason topic?

If anybody really wishes to drive a near 700-hp car, you might as well build a cage for it or better yet, buy a second-hand NASCAR runner, which have been tuned-up and reinforced all-around properly.

The Z06 is as close as it gets to the upper limit of a commercial street-legal vehicle in IMHO.

I hear Borla makes some good ones for your car.

Hey well as long as we are talking about race cars. I think for your average enthusiast who cant afford cars like Porsche,Ferrari,Lamborghini etc. The alternative is to buy a fixer upper. The imports like honda civic hatchbacks 89-95 are excellent cars to supe up. A very light car , with an engine yielding 300+ you can easily hit the high 10s to low 11s in the quarter mile. Throw in a shot of nitrous and you got yourself a mini ferrari. I personally like the Toyota Supra 1995 which after upgrades will still come in around 40 to 50 grand.

The Ford Mustang 1989-91, chevy camaro iroc 86-92, honda civic hatchback 89-95 are all pretty good poor man race cars. Heck you could probably beef up any car youd like if you had the money. I know a guy with a ford fairlane that runs in the high tens low 11s in the quarter mile. Its one ugly car but he has one sweet engine under the hood.

i had an 86 IROC about 10 yrs ago. pulled the 305 out, and put in a nice 350. that car would scat.

once the performance bug bites you, it's got you from then on.

RIC, great points on weight distribution. just another reason i had to have to Z06. perfect 50/50 balance. they even have the battery behind the rear wheels to help make it work. it is capable of pulling well over 1G in the corners, not to mention the mind-numbing acceleration out of the corners. :twisted:

89 5.0 mustang here

. For its day, it was a "fast" car. Now, I have to be careful about all the little imports with spoon engines and turbos.

Like what hailskins was saying, its all about the power to weight ratio. The one thing you can't forget about though is gear ratio. Given a pair of cars with the same HP/weight ratio, a car with 2.73 gears running a car with 3.73 gears would theoretically lose the race. This is because the car with 3.73's would be able to spin the wheels faster because of the lower gear ratio. The car with 2.73's, however, would theoretically have a higher top end because it wouldn't top out so soon.

Chris Luva Luva · Post by **Chris Luva Luva** » Sun Jul 22, 2007 6:27 pm

I won't pretend to know as much as you guys but the Honda S2000 also has a great weight distribution ratio. I was considering to get one as a daily beater but I opted out.

H6, I hope I get to see your car one day. Congrats again, I really hope she treats you well.

The 5.0 with the right modifications and additions can still whop some you know what. The real question is do I want to drive a dragster mustang around everyday? How much is gas gonna cost me everyday? As is a 5.0 I believe gives you around 10-15 miles a gallon. At 3 dollars a gallon you are lookin at a small fortune just to drive around to and from work everyday yikes!

But for those who have the wallet or those who would rather hear there engine purr than pay rent tune to your hearts content baby!

One thing for sure. The best thing to do before buying parts for your car is to get a laptop and a program called RPM analyzer by Performance Trends. Basically your engine spends most of its time in a certain RPM range, the software will tell which RPM range your engine spends most of its time. You want to tune your engine according to which RPM range it spends most of its time in. Anyone who is serious about high performance should consider this.

I have a focus as a daily driver. The mustang already has mods in the form of cam, rocker arms, throttle body, full exhaust etc.... It's also been lowered and has Koni's on all 4 corners. It has an electrical problem right now I am trying to sort out. I am basically at a point where I am going to drive it until it breaks and start over. I would also like to install a turbo kit onto my car. I don't want any more than say 500hp at the wheels. Anything more than that is just too much for the street for me. So I am thinking rebuild the motor and maybe get a set of TFS heads and holley intake and then slap on the turbo. That will be enough fun for me.

I think your close. I just talked to him. He said they had it on the Dyno at 11psi. and that was pushing 800hp. He also said he will turn the tubo up (once everything is right). At full boost it will be pushing 22psi.

It will be used for weekend fun. He has a Bronco for a daily driver, the Camaro is a toy.
