what are the horse power and torque numbers for the spec engines???

 

are gussets alowed in the roll cage??

 

well thats all i can think of for now your help would be apperciated

Hi, will try and answer some of your questions. We just built a 1987 camaro that had fuel injection and changed it over to a carbed spec motor. We left the factory tank in,but removed the electric fuel pump from the tank and replaced the pump with a new line. Also on fuel injected cars you have a pressure and return line. The return line must be vented, or capped off and a vented cap must be used. As for fuel pickup, some guys have had problems with the stock tank when the fuel gets below 1/2 tank, we have run ours at Thunderhill and at Infineon down to 1/4 tank with no problems so far. As for installing a carb you just have to do the tank, and put on a mechanical pump on the passenger front side of the motor. Run your fuel lines, which should be braided, and hook them to the carb. As for horsepower and torque, we are about to dyno ours and I will let you know.

Most everybody. Installing a cell into a Camaro is alot of work. You'll cut a hole in the unibody, then mount the cell, then try to seal up the cell with a firewall. Yikes! Unless of course you just get the 'custom' FuelSafe cell made for Camaros, but I think they're over $1,600...

Other than the spec parts in the rules, you have to do the fuel pump (as mentioned above). You'll also probably want to do 3.73 gears, because...
what are the horse power and torque numbers for the spec engines???
HP will be around 200-220, and TQ will be around 260-280, going by what the other carbed folks have.

 

Good luck with the buildup!

Hey Ska, I am currently running a carbed '84 Trans-Am. As mentioned earlier, you want 3.73s so you can keep up with the more torquey guys on the starts. Also, the carb motor will pull to about 5400 so you get more revs than TPI cars, thus making the gear change even more cool. You don't need to shift as much with this set up as taller gear ratio cars. Randy's Ring and Pinion has a deal for an extra $30 they will replace the gears free for as long as you have the car as long as break in goes properly.

 

I have it from a very good authority on safety that the stock f-body gas tank is in a good place from a safety standpoint. I have never had any trouble with hiccups starting with a full tank before every race.

 

The new 2005 rules allow a 1" spacer for carbs, that is very important for you to get max torque according to the dyno of a carb car this year.

 

I would start looking for a G92 rear so you can get the Zexel Torsen T2R posi (best). In the meanwhile you can weld up the spider gears on whatever you are running (poor man's locker). See the previous threads here on rear ends for more info.

 

If you need a seat IO Port will have Kirkey's on sale Dec. 1 Wed.

 

Welcome!

I had the very same question come up as I was reassembeling my car..... and before I spent the money (vast range $150-$1600) or more..... i am paraphrasing here..... some local yokel builds a steel or aluminum box....... then puts the various neaessary fittings on it.... makes foam available for price ...... and calls it a safety fuel cell

reporting to few if any safety compliance departments runs an ad and sells them......... on the other hand we have The General making and mounting their fuel tank and then goes about destroying many fine automobile......spending millions of dollars.... so that BIG BROTHER will allow him let his gas tanks along with rest of the car on HIS highways..... which would you rather have "BuBBa's Safty Sell" or one that is part of a cart tested every way they can.

 

Now if you plan to run ITE or AS with that other group you will need a a cell and a few other things..... but I found all their "volunteers" grumpy in their advanced age so for me I will stay with NASA and get on the track when I can and be treated with some common curtesey......this may be the one thing that is better stock than after market (at least at a sensible price point.
