It's been a while, but I'm back up with a new setup. Boost on this run was 42.3psi peak, falling to 40.7psi. I'd like to note this is on GSC S2 cams. I believe my setup is currently out of cam as 41psi peak on the previous run made the same whp, but 15wtq less than the 42.3 graph below. I'd also like to note that the vehicle weight is higher then usual on my previous graphs as I had 2 passengers in the car with me.

Nice!! I didn't know that was your car when I saw the dyno graph somewhere else. When do you think you're headed to the track?
I've used the .82 and the 1.03 Tial now on mine with this turbo but have run into some kind of bottleneck, I'm thinking about going to an external wastegate dump as I'm still using recirc on it (full 3" exhaust)- I want to try to get this swapped out soon if I can manage and get another track day in.
Thanks. If your still running a recirculated waste gate setup I guarantee you'll make more power dumping it to atmosphere. My bottleneck obviously is the s2's. I could swap in s3's and gain another 40whp or so, but I'd also be giving up 300-400rpms of spool. Not a good trade off for a street car IMO.
I'm shooting for track times in November. Still need to get a new set of slicks and I'd prefer cooler weather. Racing in 90deg heat is no fun. Hoping for 151-154mph trap speeds with a 9.2-9.3 et in mind. Have you ran your setup yet?

I might pull the trigger on that then. I'm also on a 2.0 but with the big AMS F1 intake and S3s, dynojet it gets 830-835ish whp and won't go any higher with either hotside, 47psi on the .82, but on a hot day it couldn't actually get there on the 1.03 it would not get over 43-ish for boost. For the track, I'm nowhere near you for 60' or times, trapped 147 the last time out on a stock final drive and 10.0 but with a 1.62 60'. I haven't tried it on the 1.03 hotside but might go back to the .82 with a external dump since that spooled 500rpm sooner with the cam gears at 0.
As a side effect, the bigger hotside comes in so much smoother that I can actually hook it on the street in 3rd without dialing the boost back, it's just not as fun to drive
Damn Ryu, long time no see... glad the car is running well! Looking forward to track times!
Thanks Freddie. It's good to be back. I'm looking forward to track times as well. Hoping for low 9's.

47psi on the .82 hotside huh? My best pull was 791whp, but 780's was repeatable. S3's are supposedly good for 41whp over my S2's. That would put me at a consistent 825-830whp. Makes me curious if the whp would go up a bit higher with another couple of pounds forcing the air in. Maybe I'll try 43-44psi just for fun one night and see. 41-42 only yielded a 15wtq gain, whp stayed relatively the same, but with the virtual dyno at this level, it may not show a definite gain at the very top of the graph if their was one.
Side note: 1st-3rd gear in Mexico yielded complete traction.

Same evolution I've been going through. Ran .82, went to the 1.03. I also recirc my O2.
I've got a magnus intake manifold sitting around, and there's no way I've venting O2 before seeing the difference that makes.

You should just go to STM650 cams you will make more power then any of the above listed.
