Two turbos from IPOS for the B48 Supra that I'd consider if I had a 2.0

Never driven it on the street tbh. Just trailer it right to the track. But yeah it’s great. Response feels just like oem but with more power. 0 perceivable lag in any scenario compared to oem.
I get 570whp at 24-25psi with no PI on 109 with the DAW. That’s a conservative tune for pushing wot for 15-20 minutes straight.
With PI you can probably push the turbo to about 30-31psi.
Overall, it’s a similar size as a Pure800 and I think you could get a bit over 650 with a conservative tune...
As @Awales74 points out, e100 is impractical compared to e85. It’s also only very really useful in certain scenarios.
If you really want the potential for extra performance, then use e85 ethanol blended with race fuel. For example one ethanol 117r.
You’ll need to tune specifically for this and...
That Armaspeed intake is super nice and a great deal with that sale.
I've got the Eventuri, aFe Takeda, and Injen Evo2300 and the Armaspeed is100% what I'm leaving on my car.
I’ve purchased the cheapest Amazon spacers in various sizes and used them on track at COTA multiple times and never had an issue. If they’re solid aluminum and they fit then they’re probably fine.
Wanted to make it to FL to run all the tracks there before the season started but unfortunately my car wasn’t ready (still isn’t ?).
I’m trying to do 9 Gridlife events and maybe all 4 GTA events this year so it will be pretty hectic and won’t make it to FL until a bit later.
Probably will head...
The high df Verus splitter pairs perfectly with the spage wing. You can run the wing without a ton of angle which is a lot more efficient. It feels very stable without getting a lot of understeer. Overall, the setup felt very balanced. Front downforce felt good.
The verus wing works fine with...
1-1.5s at COTA. Increasing the rear wing to compensate helped but didn't totally close the gap. Subjectively, the rear end felt more responsive with diffuser and less wing angle than just running the wing with higher aoa.
was running 2:26-2:27 laptimes on stock power at the time for reference
Vibrations will cause the mounting nuts that are closer to the front of the vehicle to loosen. When this happens, the entire diffuser will slide down slightly, get more air going over the top of it, vibrate around, etc and eventually loosen the other mounting nuts. Then eventually the nuts can...
