Re: L98 TPI 350 endurance race combination

Couple questions. Is turbo charging out of question? If not, it appears by far the way to go based on their point system. I don't have any experience with turbos. And from brief discussions with those that do I don't think it is a great match for endurance racing. Low boost would be easier, and the...

Re: L98 TPI 350 endurance race combination

5x5 won't work due to wheel availability. No one makes 18x10.5's in that pattern while I can get Vette repros in that size fairly inexpensively. Tires do more for handling than about anything else, so combining 315 up to 335 tires with an intelligently modified suspension will provide what it needs ...

Re: L98 TPI 350 endurance race combination

I'm familiar with the Mexican Monte SS but there is this; 2.1.1. Race entry is limited to mass-produced (over 1,000 units), four-wheeled vehicles certified for US Or Canadian street and highway use at the time of the vehicle’s manufacture. I'm assuming you couldn't buy one new in the US, so it appea...

Re: L98 TPI 350 endurance race combination

As far as bitching about the rules, I should note not all cars start at the same base points. Stuff that is naturally fairly quick stock start at higher points so they have fewer to play with. Older cars, especially domestics, are valued fairly low as they were not built for road course work. A few ...

A V belt powers the mowing deck on my 27hp garden tractor, so yeah.

Re: L98 TPI 350 endurance race combination

On a 400 the TPI is going to be 25 points if it's factory or a FIRST as the Monte never came with it factory and it wasn't offered on the 400. However, and I stress this again, I don't need, nor really want, 450+ hp so spending $1500 or whatever it is for the FIRST is just a waste of money. I figure...

Re: L98 TPI 350 endurance race combination

That's a lot of info. Thanks! Will be a big help. I've looked through thirdgen a bit but finding actual builds has been difficult as most of the TPI section is troubleshooting and such. The rules are difficult to explain so I'll post the pertinent parts here. The full rules are here; https://champca...

Re: L98 TPI 350 endurance race combination

How many points to run after market runners? I assume you can port anything that you want? You can find a great thread on here on what a max effort TPI porting looks like and it's a horiffic amount of labor; I'm guessing it's why so many max effort tests focused on TPI intakes instead just send the...

Re: L98 TPI 350 endurance race combination

Here are some pics of the C3 to give an idea where it was and just how gutted some of these cars are. The Fast Burns are now gone as mentioned above due to a points increase. https://i.ibb.co/VLZD6nh/IMG-2183.jpg https://content.invisioncic.com/r115480/monthly_2020_07/1001938230_Annotation2020-07-09...

Re: L98 TPI 350 endurance race combination

It's going to be HARD to run with modern Japanese sedans... especially with their all aluminum DOHC engines, advanced suspensions and light weight... and that's without even considering fuel mileage and 'family car' fuel tanks. I would think a Honda Accord, Acura equivalent or similar offerings fro...

Re: L98 TPI 350 endurance race combination

I'd look at pulling all the fuel economy tricks you can. Including/especially running the latest model injectors you can find. Toyota was running Denso UC injectors Denso the 00's and their tapered 12-hole injectors were good for notable response, economy and emissions gains on the ev1/ev6 equipped...

Re: L98 TPI 350 endurance race combination

From 1988 thru 1992, there was a 1LE Camaro option with the L98 that was built for endurance road racing. It was also part of the old IROC series too. The 1LE package even had a fuel tank with dual pickups for preventing any fuel starvation through cornering. https://www.hemmings.com/stories/2014/0...

Re: Best 70’s vintage SBC build.

What about a 1970 350 LT-1 based engine ?? I believe that Trick Flow make a newer aluminum head that is made to look like the old style SBC heads.Its pretty easy to paint them the same colour as the rest of the engine so no one would ever know the difference. Use a new tech piston and ring package ...
