here are few pics of my 8 points roll bar for convertable vette. We are going to put in the door swing bar next Sunday. after that we are going to hook up the turbo oiling and some electrical wirings. Then we should be firing her up.

 

 

 

Bruce, yours looks like mine.... I wasn't able to get the last two points either... I'm not sure what I would have hooked them too....

 

hi Tony
yeah it should look like yours, since they are all 8 points . But since my car is a convertable. We need to do some bending. Luckily, Rick has a mandrel bend machine, so he was able to put a 20 degree bend for the back. That 20 degree bend is needed to clear the convertable lid. Over all I am pretty pleased with it. Really like the look and the extra safety.

hey Tony
how is your new custom cog drive? I know while a go you bought the cog pulleys and say to be install on your car. I am curious how it turn out??

Bruce

 

It's all done, works like a champ.. no problems whatsoever. The only winter type project I have going on is I think I am going to send my FAST box back and have it upgraded to SEFI in order to handle bigger 160lb. injectors (I'll never make the kind of power I want with my 83lb. injectors.), move the battery to behind the passenger seat, build a bracket to mount my FAST box and MSD where the battery was originally located, and lastly to build some ducting to force air through the intercooler and radiator while moving down the road. We had a small break in the weather a couple of weeks ago and I noticed the car would not cool nearly as good going down the road as it does at idle, clearly an air flow problem... no big deal..

I also bought some variable pressure sensors that will engage my secondary Aeromotive fuel pump when it senses boost. I had it set up on RPM... which does not work very well because my car breaks the tires loose really bad (on these cold roads anyway) and the cent. supercharger doesn't build any boost until it senses a load on the motor (which it doesn't when the wheels are spinning) so all I get is a black cloud of smoke behind me... I have mounted two of these switches and have syncronized them together to engage at the same time, this way if one switch goes bad the other will still engage the pump.. cheap insurance.


I'm ready to tear it up this summer... it's about time...!!

 

I would imagine the forward points of a 4 link we don't have. The rear bars are welded to the mounts of the rear axle (batwing). makes the car real stiff. To make the top work I had to drop the main hoop kind low, good thing Bruce isn't a tall man or his head would be higher than the hoop. With the seat all the way down bruce's head (inside a helmet) will be just below the bar. A good thing considering all this talk of doing 200mph.

 

Very nice!!

 

I think that Vert. roof is coming off at 200mph!!!!!

 

Packin' as much heat as bruce is, I think he'll just do it with the top down. Just like them 9-10 second passes

 

Actually, the picture I received with my eight point bar shows them angling downward from the main hoop inward toward the structural member that typically runs over the transmission which is disposed from one side of the car to the other, which of course we don't have. Someday when I put a straight axle in I will simply bend another bar that humps over the trans (by cutting the inside of the passenger compartment for fitment) which will them provide a hookup point for the other two roll bar connectors as well as a mounting point for the trans, which will likely be a strengthened T56... That way I can solve a few problems at once. I was out on Digital Corvettes last night (late) and found a guy who put a straight axle in his C4. His install looked very simple and used the same fout link points we now utilize along with adding a panhard bar which looked extremely simple.

Don't use the 160bls injector. That is way over kill and idling will suffer. It is just way to big for street car. A guys in the camaro forum use a 96bls Delphi injector and his twin turbo made 1005rwhp with out any fuel problem. Also they are a few guys there use 160bls and did not like it. Do just be ware of that before you go ahead and buy those that *** injector.

Hi Bruce,

Do you know if they are running in SEFI or bank to bank mode? You certainly cannot run those big injectors in bank to bank. I'm thinking about going with SEFI anyway as I think it will help the car not load up at idle... In bank to bank mode the injector actually fires twice for every 4 cycle process of each cylinder.

If you do the math (including parasitic loss for drive train, etc.) you can only come up with 840-850 rwhp using the 83lb injectors. If I want to run with those TT vipers I'm gonna need more than that...the 95lb injectors are good for a little more as you have stated...

Tony

 

I don't know or remember what ECU mode they were running. Since you say bank to bank can not run those injector, maybe that is why they did not like 160s. I know your combo gonna make some serious power. What is your power target? 1500hp?

Bruce

 

Anything over 1000rwhp is gravy to me.. 1000 was my goal, but if it ends up greater than that's ok too. With my current pulley setup I will be maxing out my supercharger at 7000rpm. which should be right around 1500-1600hp. at the crank...

 

horsepower addictions....

 

96 lb injectors with a higher static pressure is where it's at. I ran 160's on my Buick with a B2B FAST. Warming the car up is where they'd kill the plugs on me. A good tuner can get them to work, but they aren't fun.

The 96's had awesome manners.

 

Will they even let you run sub 10 sec without a hoop to the windsheild?

 

Yeah, those TT Vipers are pretty dang fast. Two places not to far from my house( Hennessey and RSI) that build those cars.
