300+whp 2002 miata custom turbo kit project

The timing map will not tell you a lot since it's an FIC. The map will only show the amount of timing that is retarded over the stock map at full load like this:
-7 -7 -7 -7
-4 -4 -4 -4
-2 -2 -2 -2
0 0 0 0
If you still want to see it just ask and i'll post it
As for the numbers, the only comparison I can give you is 2 years ago my 7mgte supra at 20psi with a t66 did 470whp on the same dyno......

The Escort GT/Protege guys have been running over 300whp on stock BPs for many years now... (Street cars only, for whatever that's worth.)
I don't think this car is actually over 300whp, but i'm just sayin'.
Stock motor @ 312whp
Stock motor @ 339whp (There's other videos of this car around)
Again, just street cars and i wouldn't expect them to hold together for decades, but it's possible in general. I just don't think it's truly possible on this low amount of boost. I'd expect OP's numbers from probably 15-16psi.

The compression is secondary to your argument. Stock rods is stock rods.
I don't remember what compression my BP05 was. I threw it in the trash because BPs make my ***** soft.

I said I don't know. I know that the festiva I tuned was never able to hook 1st or 2nd, and by the time it got to 3rd-5th it was well past peak load and operating in the 5-7k range. Find me one other 300whp 10:1 bp6d that held together for more than a few dyno pulls and didn't splooge its internals. That's all I'm sayin

Maybe the reason his hasn't bent/thrown a rod yet is because his peak torque isn't until 4000rpm?
Based on what little engineering knowledge and engine knowledge I have, I think 220wtq at 2800rpm is harder on the rod than 220wtq at 3500rpm.
That said, everything about this thread makes me think this engine is living on borrowed time. It's hard to believe he wasn't hearing any knock on 91 octane, on basically the stock timing map retarded 1*...

It was a gt28rs sized turbo (hks gt2535) that hit peak boost at exactly 3500 actually.
I know what you're getting at and I agree, but from his plot this turbo doesn't look all that lazy at all. Looks pretty darn good actually. Whether the plot is optimistic or not is a different question, but I'm pleasantly surprised with the ct26 in this case. I'm guessing the custom tubular mani and ewg are helping a bunch
