Re: 1990 Indy turbo

GM preprogrammed the engine computer to interrupt fuel when a certain speed was reached (it has to do with the speed ratings on the original tires). My '88 would cut fuel at 120mph. The first time it did it, I freaked out, the sudden deceleration made me think something came unglued in the engine! I...

Re: Engine hoist

I always found that lifting the body off the engine/trans and subframe was easier... Just set some jacks stands under the subframe, disconnect the battery, all hoses, electrical connections (mark what they go to!), shift linkage, and fuel lines then unbolt the struts and calipers from the knuckles. ...

Re: Center of Gravity

Yeah, I understand that. Well, I'm interested in optimizing the stock suspension since our layout ( MacPherson front, semi-independent rear) is very widely used and can be highly competitive when properly set-up. If we can determine CoG it'll be a benefit for all in our community interested in all f...

Re: Center of Gravity

http://www.thecartech.com/subjects/auto_eng/Center_of_Gravity.htm This page has some good info for finding the exact location of the CoG... I'd like to perform these measurements, I really would, but my car is almost an empty shell right now. I'm doing some rust repair and a re-paint and getting so...

Re: Center of Gravity

Thanks! I just read it and it's very helpful for finding the center of gravity within the wheelbase, but as far as the height of the CoG, they make a blanket statement about using the center line of the camshaft as the approximate height of CoG (they're talking about muscle cars and hotrods that don...

Re: Center of Gravity

Here's an interesting tid bit from the engineers at Whiteline, arguing that 0% anti-lift is a positive thing for the front end of a WRX as it will understeer less while accelerating or braking during a corner. Before assuming that this would be great applied to a Beretta I'd like to take readings on...

Center of Gravity

Hey everyone, I'm looking for the center of gravity of our vehicles in the effort to improve vehicle dynamics. I know most people just lower their cars an inch or two to lower the center of gravity (I've already done that but found that the car seems to squat on acceleration more than I'd like.) and...

Re: 1991 Corsica Hatchback, 43k, $950 Hamilton, OH

I wish I could get this... I wanted to buy one of these and do a Z26 bumper swap on it... I had posted on here like two years ago looking for one.

Re: Indy/GTU Centercaps

ok, I don't know what suspension you have, I'm under the impression that you have the FE7 since you have a GTZ. Here is a pic of what I had on my strut brace.Image
It needs to be tweeked some but I liked it.

Re: Indy/GTU Centercaps

3x00, I would agree for the most part, but what about impalas with 409s? There never was a factory 409 Corvette so I would assume the crossed flags was simply a performance indicator. You misunderstand what I meant with the option codes... I should have written it like this; Z51 if you have that sus...
