lsxr vs lsxrt results yet? Anybody get dyno results of the lsxr vs the lsxrt? Im buying either one this winter for my car and don't mind cutting it up for the lsxrt if it is that much better than the car fast (FASTLSXR). I don't wanna cut my car up for 10rwhp and 5 flbs. Anyone have results? You can pm me info if ya want.

The truck intake is for a truck for a reason; they need the low RPM grunt to haul around trailers, payload, not to mention a 6000lb dry weight.
IMO; it'd be overkill and a waste of time and money to put it on a car. I don't foresee any difference or gain (Over the LSXr.) The LSXr has all the plenum volume you should need.

My understanding was the fast truck manifold was much better because they did have the room for better airflow. It wasn't because it was tuned for trucks. Someone was going to/did test it but got bent out of shape because someone was giving them a hard time on the forum so said they wouldn't post the results. I would love to see a comparison.

Then you dont want to run the LSXRT. Its the most powerful intake that FAST makes, but its not worth hacking up your car for. Its the one to pick if you have enough hood clearance, otherwise just run the car intake.
The runners in the LSXRT are straight, and the runner in the LSXR are curved to fit in Camaros and Corvettes. Air doesnt like to turn........
The LSXRT doesnt make any low end grunt over the others, it just carries power better because of improved runners and increased plenum volume. It doesnt have anything to do with being a truck manifold, it has to do with the amount of space avaliable to straighten the runners.
Edit: We posted the same info at the same time....haha, but you are correct.

But the LSXR intakes are basically an ITB intake that shares a common plenum, and the truck intakes have straight runners.... -From what I gather. When I took my 102 apart I was in awe... Such a piece of engineering, it's amazing..

I wouldn't mind cutting my car up for it, but it would have to consistently beat the lsxr by at least 20 rwhp. It would be nice to see some dyno results though. I'm just going to run the lsxr and a 92.

^ Seriously dude?? Why even respond..... childish remark. ........... Not everyone DRAGS their trucks. There may just be a couple people out there who have added LT's and a FAST intake to their 2500 HD's so they can tow their trailers a bit easier on the HW.

Not cutting my car up for MPGS lol. If you can get some graphs for me I would be greatful. My car is max effort for the most part and will stay that way once I do a stroker motor.
