176 kw on 10psi at 5250rpm

very very happy

236hp? Wow... is that a corrected "at the crank" figure, or is that at the wheels?

If that is at the wheels, that is EXCELLENT for a stock engine on 10psi... especially with a GT2560. I will be fitting a stage 3 kit with 2560 to my NA8 in december and if I can tune to 210rwhp at 10psi, I will be over the moon. I am expecting more like 200 rwhp.

Congrats!!

OK i'll bite...

Quite honestly, these numbers are astounding. A little too astounding to be sure.

Peak power at 5300rpm is unusual. I would have expected it at least 1k rpm closer to redline, at least having regard to the other dyno charts i've seen for similarly modified cars.

Here is a great source for MX5/Miata turbo dyno charts:

Whoops - wait, SO much fail. I didn't see the key - blue is power, green is torque... d'oh! :oops:

OK so the line isn't outrageous in shape - just very impressive on power.

How much timing has he tuned in? With a lot of advance and an awesome exhaust, I could see these numbers being possible. Lots of advance though, and you run the risk of detonation, etc - but your tuner knows more about this than me i'd bet...

Just checking that everyone is making their judgements based on the knowledge that this is a HUB DYNO.

So in other words, we are talking 236 bhp (after conversion)?

I honestly dont want to get involved in any sh*t fights over this. I am not claiming anything just showing what I've got from them.

i dont know what difference a hub dyno makes.

I have only dríven it home from the shop so far so have a limited feel for it (and wont really give it it's first squirt until I am on a good open track) but I can vouch that it gets on song very early. This was always the plan though. You now just row through gears like you are facing a truck full of japs with a bolt action rifle.

From day one this build was always about response and a linear torque curve. It was never about peak power

vvt or vct- can never remember

the oem ECU runs the vvt/vct

oh, the exhaust is a work of art- 3 inch stainless with one muffler- no cat

The type of dyno setup can effect the final figures.

Regardless, it looks like the install has gone great! Congrats! Would love to hear updates - have a similar install coming up myself
