Sweet........................And on a 1.6L.
Your're my hero Batman.
You said your going 30psi. What are you doing for a tranny.(Sorry if you posted it already)

Good Luck!

 

I dunno, maybe this summer. Been talking to Bryce on IM. He said... Well, I can't say anything here. Still building that stock miata?

 

nice numbers huh

 

Quaife transmission I think...

 

Yeah, It should be driving in November. It's taking a lot longer to get out of the chassis shop then planned.

 

6 speed is good to 400whp.

 

I know it is, an that's a possibility too. Here is a teaser...

 

+1 don't get a quaife gearset.

 

Reason for that? Besides the crazy cost...? Thanks!

 

Wow! Very impressive numbers
I was pushing 20psi to get 307 rwhp (Dyno Dynamics Dynometer) on my 1.6 while you are almost there with 5 less psi

2 questions:
1) What did you do to use less boost for almost the same power?
2) Someone mentioned that the 6spd g/box is good for 400rwhp.
What are the facts for this based on?

Does someone have 400rwhp & a 6spd g/box? Anyone?

jtothawhat - I hope I haven't hijacked your thread in anyway

 

1. Well i dunno what turbo you where running but his is sizeable this freed up more hp per psi becouse he was getting a cooler denser charge pre IC.
2. Miata 5 speeds have case flex and gear issues man we flex the case and breack the gears i know my bellhousing has numerous stress cracks in it. And the 6 speed uses stronger gears and a stouter case. I have seen on here and other sites of people running 400 and even into 600+ hp on them and working fine.
