Until we get confirmed stock boost pressures and stock turbo compressor sizes for the B58M3001 2021 models to compare to the 2020 model we will never know. I can tell you this though, the difference between 11.0:1 Vs. 10.2:1 compression is about 2.4%. Given the same boost on same turbo sizes the...
I called into BMW and Toyota and neither of the parts departments could give specifications on compressor sizes for either part numbers. I was told by a turbo manufacturing company that the actual compressor wheels are in fact different in size as well as the hot side too. Stock turbo on B58B30C...
Could you please post a data log and dyno for a tuned 2021 MKV. Didn't know that tuners could get them before a dealer could guess I live under a rock these days. LOL
If you were going to a GT3RS or GT2RS maybe but an R8 you would be disappointed by. Your Supra when properly set-up and tuned can keep up with most exotics and even fair pretty good on a track. Where I live Porsche and Audi are a dime a dozen. Hell, there are more Ferraris, Lambo and McLaren...
I bolted a down pipe on my 2020 with no tune and made more than 40whp for $299 after my first 800 miles on the car last year LOL. I'm certain my $299 bolt-on made more power than a stock 2021 model and I paid less then what people will pay for a 2021 model off the showroom floor even still. I'm...
The 2021 MKV Supra's B58M3001 uses a larger turbo and the part number is (11657934387). The 2020 MKV Supra has a smaller turbo on it's B58B30C motor and the part number is (11657934332). The factory boost pressure is also higher on the 2021 model MKV Supra as well by about 4-5psi.
For the...
Maybe lack of clarification but not dodging. I Know what I posted and when. My statement still stands. The B58M3001 doesn't make more power than the B58B30C (given the same PSI and turbo)*. Both the B58B30C and the B58M3001 blocks are identical except for the pistons, rods and head. 3.0 / 11.0:1...
No that was my point from the start, the fact that 2 motors with the same displacement and cylinders, one having a lower compression and the other having a high compression would prove that the higher compression motor will achieve more HP at the same PSI levels. Toyota has their own head's up...
I get it, you don't have a car or a Supra but people will think less of you when you post out of your ass parroting the car and driver articles you keep reading. How many personal A90 Supras have you data logged? How many A90's have you driven? Owned? Worked on? Anyone can Google misinformation...
Well I have boost readings from my car through data logs and different maps and I have read through various sites that the 2021 model has increased boost pressure over the A90 models as well as a different turbo. Have no idea if the dyno run here is flawed. It's one dyno run and none of us have...
Again, you missed the entirety of the debate. The new block will not make more power given the same boost pressure on the A90 B58C. 0.025 inch increase in head gasket thickness only lowers compression by around 0.5 points anyway. It's irrelevant though, as it's the final compression ratio that...
The 2021 3.0L i6 is running 5psi more than the A90 stock boost pressure only reason for the difference. Same boost pressure my A90 MKV made 430whp. So tell me again how a low compression motor makes more power than a high compression motor with the same boost? :popcorn:
