Nice one, when do I get a drive? :mrgreen:
If you had access to a car like this, would you take it back right away? Neither would I.

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

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 :)
