Torque gets a car moving, horsepower keeps it there. Torque is more important on a track since you are slowing down and speeding back up the whole time.

I think I honestly liked the gangsta rap VRT used to use in their vids, as opposed to Tom Petty, lol.

So Ed,

What's your take on sticking with the 530BBs for the street/track? What's the point of going with the 700BBs if you've gotta de-tune to make it useful for street/auto-x/etc (I guess everything except drag)?

John:

Here is the comparison Dyno you requested on the JWT BB 530's. Both cars tuned by Jim Wolf and Clark Steppler, on the same dyno.

Once you decide you want a car that is not a trackable street car, but a car that is a streetable track car.


I think that when you are committed to a stealthier street car with occasional trips to the track, the JWT 530 is the way to go. Especially with an adjustable boost controller. The 530's on the street at the wastegate springs is plenty of punch. Or, if you are going to run the car with a stock motor on low boost (no way can you use the 700's on a stock motor!). Or, you are not prepared to make a LOT of mods to the car on suspension and handling in addition to the bigger turbos....this last point is important for safety I think.

Once you decide you want a car that is not a trackable street car, but something that is a streetable track car, the 700's take it up about another 100 ponies and lbs/ft at the rear. Why do that? Quite simply, the power to weight ratio you are dealing with in running against the vettes and turbo porsche offerings is tough....they are a lot lighter. As you go through your gradual evolution in driving and begin to extract more and more performance out of yourself, and thus are able to manage the power and potential of the set up, you advance up the little steps to where you are not just driving against fast cars and good drivers, but really fast cars and some excellent drivers. In the 530's, the car most certainly holds its own, and then some. In the 700's....you have some advantage, particularly in the acceleration demand beginning over 80mph, and in uphill climbs. Is it a difference like between a Model A Ford and a brand new Cadillac? No. But it is a difference you can really feel and see, and with some track time actually use.

I do not recommend it for the street. You can of course have it...that is what business is in business for, to sell you stuff that you can afford to buy, not stuff that you need.
But to really "balance" the power you absolutely must do suspension and braking mods in my view, or you are being stupid, and that takes the overall cost into a dimension that makes very little sense for most folks. Maybe you don't have to go AP Racing...you can go with the outstanding offerings from StopTech. You don't need adjustable front A arms or rear control links or strut tower bars. But you do need upgraded anti sway bars, and much wider wheels and tires. You don't need a mechanical limited slip, but you do need a very strong clutch upgrade and flywheel. Cooling system upgrades to the radiator, and power steering are essential. Then you should think about higher capacity oil pan. There is more, but you get the idea.

At the end of the day, we each get to do what we want, and there are a lot of very happy people out there that do stuff some of the rest of us think is idiotic. And for some of them, the impression is reciprocated back to us!

Cheers,

Ed
