will my TR230/236 bleed too much boost?
99-TR230/236-112 Thunder Racing Custom Camshaft - 230/236 .590/.598 112 LSA 2400-6800 RPM Power Band. Excellent mid-range & high RPM power. 3200+ stall, 3.42+ gear, computer tuning required. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended.
it ended up being a 230/236 .589/.598 11.9 LSA
looking into a SC..... would i be better off getting a higher LSA cam or could i stick with it?

For a Supercharger I think that will be a fine cam. I don't think the ovelap period is as critical in a Supercharger application. With a Turbocharger, the exhaust back pressure from the turbine housing will try to hold some of the exhaust gases from exiting the chamber; then during the overlap period possibly force the residual exhaust back into the combustion chamber contaminating the incoming intake charge.
Beacuse on a Supercharged application the higher pressure is on the intake side, the overlap period may allow more intake charge in and evacuate the combustion chamber of residual exhaust gases .

All cams will work with nitrous, or forced induction but they will not be as efficient as a cam intended for that application. People think that if they install nitrous or forced induction on a motor with a N/A cam that it will not work at all. If you are going to install forced induction setup then it is best to get a cam suited for that application....

Im using the same cam in mine. Unfortunately Ive never had it on a dyno.
It idles a bit lopey, but strong. Sounds good. It doesnt seem to pull too well until about 4000rpm, then it pulls hard to 6300rpm where I was shifting. I did rev it to about 6800rpm a couple of times.
Unfortunately my car is off the road at present, so I really do have limited milage on it.
I swapped from a LPE GT2-3. Again, due to timing, it was only installed for a few days when I decided to swap. The LPE cam just felt too tame, although Im not totally convinced the new cam is that much better all round. The LPE was very mild until over 4500rpm, although I defo should have spent more time tuning it.
Suprising thing was boost didnt seem to change a great deal swapping between the 2 cams.
Here's a couple of links from down under, that suggest cams with a tight LSA work.

That is almost identical to my solid roller, 230/236, 112lsa. It is running great on my Vortech-blown 383.
Stick with that cam! The Comp Cams tech guy helped me pick it and I told him I was going to run a blower but wanted a smooth (sleeper) idle.
I am getting 8lbs. of boost after the FMIC, at 6100rpm. Pretty much right on target. Motor rips!

It won't make more power than a smaller cam, that's for sure.
Pick up something in the 22x range on a 114 to get the overlap down, then enjoy the fact that your wife can drive your car again, and it finds it own idle in the morning.
(actually I don't mind either of those things )

You can get a away with more than a turbo setup but still nowhere near a NA engine.

Look thru cam catalogs. Even SBC cams as they have more listed application specific grinds. Find a supercharger spec that seems closest to your LS1 plans and look for similar grind data in a LS1 cam..
Or just call comp cam help tell them every little detail and they will hit the nail on the head for you.
