I have just read a lot about on first start ups with cam installs that the car has to hunt for idle and you have to feather the gas to get it started. I turned the key for about a half a second and it fired right up and idled no problem at around 800 rpms. I never touched to the throttle and it did fine. Stock tune. The car is in my sig, I was just wondering if this is normal?

I know it sounds weird, just unusual for something to go this smooth. Just need some reassurance. lol

Kinda lucky, but not out of reason. I bet if you blip the throttle it starts hunting for idle.

I just fired a 230/238 on my old 230/224 cam tune and it started and idles perfectly.

I just installed a TR230 in Aug. Mine started right up and idled fine on the stock tune. Drive it for while, it will be difficult in stop and go, it will die frequently until you have it tuned.

This makes me feel better. Haven't had a chance to drive it yet. How do you like this cam now that you have it tuned? Its hard to find any recent info on this cam.

Once the trims settle and such it won't be so easy to start. To put it basic, the PCM will kind of "freak out" when starting it for the first time with a cam and it'll do what it needs to do to keep the car running. It won't last forever though.

My cam was very similar (same lift and same duration) but ground with 3* advance so it peaked earlier.

My thoughts: killer low and mid torque, pulls harder starting around 3500rpm, 21+mpg highway with an auto, awesome idle sound

Negatives: stinky exhaust, needs open headers or close to it to work properly (3" duals are ideal), doesn't respond as well to high flow intake manifolds


Overall I think it's an awesome cam, but if you intend to keep modding I think the reverse split hinders ability to let good heads/intake shine as well as they would with a traditional split.

^^^^Thats pretty much exactly what I wanted to hear. I knew I probably wasnt going any further in mods with this motor, so I thought the reverse split would compliment the 853 heads and LS6 intake a little better than some traditional splits.

I definetely wanted a cam with lowend and a mean idle. I just have the traditional headers through ory through catback exhaust right now. I am planning on an electric cut out, so hopefully that will let the cam perform to most of its potential when I need it to.

The reverse split design was originally (and only) intended for use with stock LS1 manifolds. Back before we had FAST intakes or even the LS6, the TR30 was invented to help create a "crutch" for the crappy LS1 manifold and still make good power for a cam only car.

With the addition of anything better than an LS1 intake, it becomes a dated design. But like many purpose oriented designs that weren't intended for the masses, the internet took off with it and every body was buying TR230s for a while.

It's picky about exhaust.

I had 3"duals to the muffle and 2.25" tails. With that setup I still gained 1-1.5 tenths with dual cutouts open at the track.

I cut off the tails and then it ran the same with them open/closed.

Running a little lean at idle makes the engine run smooth, but your AFR could lean out to a dangerous level at higher RPM's.

If you wanted to know the exact AFR...just install a wideband O2 sensor.

Thanks Damian for that bit of info. I didnt know that even a ls6 would "hinder" this cam. I thought it was good for anything less than a FAST or BBK. I was going to run an E-cutout, but if Thunderstruck dropped 1-1.5 tenths just by have two cutouts, then maybe thats the way to go?

My cutouts were placed about 12" behind the header collectors. Sounded terrible and the car hated to idle with them open, but the car ran quicker so I used them at the track.

Once I freed up the exhaust after the muffler it stopped gaining anything.

Point was just to show how picky it is about exhaust... 2.25" tailpipes on 3" duals were not enough to make it run its best. 3" all the way was.

Running a cam similiar to the TR230. I have a old MTI X1 230/227 591/571 112. I had all bolt ons and a vigilante 3200 converter with 3.73 gears. I just swapped out my vigilante stall for a 4000 converter and been running TSP True duals..

I thought about swapping out a cam for a bit more top end.. And just swapping out my 3200 stall for a 4000 stall this cam can pull even more harder top end now. I like how this cam performs and drives.
