Solid Roller and Boosted applications This seems like a stupid question, but I don't know anything about solid roller setups. Will someone go over the basics of a solid roller setup and the pros and cons of using it with a turboe'd car. Why should I or shouldn't I do it?

You dont need a solid roller to run 9's on an Incon setup. Mike Brown ran a 9.8x with his Incon TT with a stock shortblock, just 6.0L heads and cam I believe. The key is to have an auto with a 'brake on it. I think Mike was running a Th400.

LOL, yeah, I know. I am getting it all installed on my car right now. Bought Mikes' old set up. Turbo and trans. Weight is my biggest concern. With me, car is right at 4,000 pounds!! So, I think I am going to need a few more HP to get me to that mark. Mike's was much lighter. Any suggestions Mike?

That will free up a lot of hp when you start pushing the limits of the kit and it will be much more efficient. Plus, it will be just as reliable as a stock engine with the stock Incon kit that way. Honestly I'd try to stay away from the motor as much as you can and let the turbos do the work. For your setup, I'd say get a nice set of ported 6.0L heads, a nice hydraulic turbo grind cam...(talk to Mike Brown about the one he ran, or call FMS- I think Harlan ran one of theirs when he ran a 10.000 on a 6 speed with the Incon.) Get a nice forged 348 shortblock, etc. You can get an aftermarket sheetmetal intake as well to reduce some of the heat caused by air restriction, thats worth some hp there as well.
Most importantly, you and/or your car is going to have to go on a diet.
You can have all the hp in the world but it isn't going to get you off the line any faster when you are driving a tank. Overcoming that much inertia is not an easy task. I hope your car already has a cage in it, because you cant add anymore weight and still run 9's. I'd start lightening up that front end (K member, upper and lower A arms, lightweight battery), you are only going to be gaining weight with a turbo setup, I'd say your car will weigh 100+lbs more. Maybe start looking into some lightweight molded carpet. Just something to get that weight down. LS1 Tech Stories

I think a forged 348 would do good......... but I would personally stay away from the sheetmetal intake unless you just want one. The Fast 90mm should be sufficent to handle the power you want to make I beleive. But then again...... if your looking to go 9's why not go with a 408 or something and use the same boost and go a little faster? Hell you won't have MUCH more money in it.

Yeah, the front end is already lightened. The back seats are gone. Its just a ton of stereo equipment. Besides drag racing, I do sound quality competitions, two hobbys that don't go together, but I don't want to sacrifice one for the other so....I am thinking the same thing Josh, I really want to go 408, but don't know if the Incon kit is enough turbo for a motor that large. What do you guys think about a 408 with the Incon twins?

Most of the people on here guess that the Incon Stage II kit (gt37 turbos) will be able to support somewhere in the neighborhood of 800-850rwhp. On a big cubic inch motor you will make a ton of torque really early, but I doubt that they will flow enough in the big end.

Dang, I was afraid of that...What were your goals with the 403 and Incons? I don't think 850 will get me my nine second pass. HMMMMMm. Wasn't there someone at Limit Engineering(not for sure on the name) that was making the housings larger on the existing turbos and thinking they were capable of a little more?

Well if you cant get the weight down, you are not going to run 9's on an Incon kit. There just isn't enough power there to do it with a car weighing that much. Especially with a stage 1. But you can run some mid-high tens possibly.

Well, alot of it is removeable, but I am just a hard head and want to run 9.99 as the car sits. Kind of like "run what you brung" LOL But, I am sure I will get frustrated enough to yank most of it out one day just to see what I can get her to do.
Solid roller stuff basically is a manually adjusted valvetrain setup. You would have to manually adjust the rocker arms to get to target 'lash.' These folks run more aggressive cam profiles and big spring pressure. The cam lobes are more aggressive and snap the valves open and close more aggressively. In addition, you can run higher rpms.
You would need:
-$900 rockers
-need to open up the pushrod holes
-clearance/gut stock valve covers for the rockers
I don't think it's a pretty advanced step for you based on where you are now. I would do more research into it.
Mike's CE/TA went 10.doh's and 9.8's all day long at 3500 raceweight so throw the car together and work on that number.

Yeah, I am definately going to try and max out the setup as is, then max it out with a FMIC, and then it's on to another motor. Is lash very dependant on outside air temperature? I'm just afraid that the 4xx route would be too much for the turbos as they sit. Anyone have the contact info on the guy that was modifying the housing on the existing Incon kits. I think his name was John, maybe the company was Limit Engineering??? With slightly bigger turbos I think I have a better shot.

You can call John Craig at Limit Engineering and talk to him about fitting larger CHRAs in your exisiting housings...I almost went that route, but decided that the money that I would dump there trying to bandaid a kit that wasn't meant to make that much power was better invested elsewhere.
