Can you share any data logs with this combo?

Are your dyno numbers in your sig the same tune and boost you are running right now?
What springs are you running on the car now with a 214/214 cam?
I dont think a 3200 stall converter is driving the turbo enough on the top end.

Your combo with that cam is totally wrong. The curve your trying to pigeon hole this turbo into won't cut it. You will be much happier and the combo will be more efficient with a roller cam provided you have a decent set of heads and a good stall converter. Your max rpm that your seeing now should be where your gear shift falls back to between shifts with your max being 6,600 to 6,800 rpm. The only shitty thing about it is the work that it will take to do it. I personally wouldn't lean over fenders and skin the front cover to put a cam/timing set in and change valve springs. I would pull the motor and do it outside the car, then reassemble.
a trade for a little more horsepower and a loss of torque,does the car spool slower?

I am currently using this turbo and in the process of swapping out cams. Car pulled hard with the 212/218 cam and never ran out of power but it is time for something custom, in MY opinion.
My new set up: (same as before with the exception of custom cam)
Long arm stroker from Dave H, Aluminum TA SE heads, Champion intake, 72MM TB, 224/244 cam
,325 RJC FM, #160 injectors, 6870cea 4 bolt, 3.5 DP with full 3" GN1 exhaust, FASTXFI with eDash, TH400 with 3500 stall, Dual intank 510lph pumps with hot wire kit from DC. I will post dyno numbers once I have it running with a Cal tune.
I have the 212/218 Rev2 from FT I will be selling along with double roller very soon. less than 200miles

Well I haven't had the turbo put on yet, I told the guy that is doing the work to just put the turbo on first and let me try it out, He said the chip should be fine for a test, If I added the turbo fast system, Bigger injectors it wouldn't give a good ideal of the turbo, As soon as he gets it on I will give my opinion, When I got the car it had everything in my post but a stock short block, It was fun to drive and run 11 teens but when I had the eagle crank and rods and je pistons and the roller cam it felt like a new car, Funny on the cam Comp said not for street use, It runs great on the street and the car went 10.60 at 126, It had a no lock Art converter and had it changed to a PTC lockup and it went 10.40 at 131 on 20-22 pounds of boost
In my sig it is written that the car made 607 HP at the wheels. Well when I went to the dyno the last time, my tuner told me there was a correction on the Dyno and that my 607 HP was more like 588 HP. After the correction was done on the dyno I did 595 HP with the CEA 68/70 turbo.
To be honest with you those springs have been around for a really long time. The heads that I have use to belong to Eric at Dynotech, which a friend of mine Claude (Too fast for you on this forum) bought off him and then I bought them off my friend. So those valve springs have done their time, and were installed on my car with the inner spring removed back in 2009. They were tested in 2009 at 140lbs, which at the time I didn't know that was too much for a flat tappet cam. Its time for a new roller cam and new valve springs.
Mike you are right, this cam is not good for my combo. Need to find some who could refer me to a good roller cam for my combo and heads. I would always make my car shift on its own which is about 5400 rpm to 5500 rpm and come in at the traps at 5800 rpm. I will have to start shifting my car on my own , especially if I need to start bringing the car in the 6000 rpm range. I always liked the rpm to stay under 6000, I find it keeps the engine in one piece lol.
The car really spools great, the same as my PT 67/76 if not better.
WOW Nat86, your car is making some crazy HP. Are you running a TA aluminum short block? How much cubic inch? At what rpm do you shift? Do you have any track times for your car?26 half psi to 27psi a few frames. I love this turbo

Sorry for all the questions, just very interested.
Thanks Marco
Hi Paul
I noticed in your sig, that one of the GN has a cam by Bison. Do you recommend that Bison specs me out a cam?
Thanks,
Marco

Nice
If you get some good 60ft, your car should rock and roll. What was your trap speed?
Are those dyno numbers on a motor dyno or wheel?
