Yeah- I don't think Travis thought that one out before posting it. If he made a cam gear that could dynamically change, we'd all have one.

Well Matt made these plots using fixed timing just like a cam gear would. He posted the plot degrees somewhere for each run. He can do angle changes a little quicker then we can because he just has to type a number in, but as far as power changes a cam gear is a cam gear is a variable cam gear fixed guys.

I was glad Matt let me use the dyno plot. Many thanks!

The dyno plots show the cam gear in three different positions. It doesn't move during the dyno run.

Now if he had shown those and said "have the best of all three at the same time!" it would definitely be misleading.

now if he had the exhaust cam gears in carbon fiber, I could put one on and satisfy the "not even using your product" requirement.

That makes sense using it at a fixed position to show the differences. I was thinking that it's always used as a variable system. Time to play with this on my own car....an email is coming at you shortly y8s.

I will have the dyno plot tomorrow.
At 20psi, word is, I am in the 300's for whp and ftlbs. Thats on a Mustang Dyno.
Tomorrow I will have the plot to scan so we can see how it spools up..

Mustang? That's like 360+ rwhp on a dynojet... at least compared to the mustang/dynojet I was on.

Default Stage 1 vs the stage 3 dyno plot

The plot is not spooled/boosted as soon as i wanted it to be. i think with the increase head flow and the Intake mod, it slowed that down a bit.

Regardless, I think these numbers are pretty bad ***.

please let me know your thoughts..

20lbs of boost.

The skinny line is the boost, with the stage 1 turbine .48 it had 313 tq and 310 rwhp.

You're still alive?

ON TOPIC:

What LB spring are you runing on the Tial? Do you have EBC? Tial recommends never running more than 2x the LBs boost as the spring you have in the EWG. Ideally you run the spring that is just under what you plan to run. Coupled with the EBC and you will not leak boost from the manifold pressure. With those combos you should be able to hit max boost around 3400-3500rpm at the latest. My best educated/experienced guess is that manifold pressure is opening you wg early and leaking gases.

My 1.6 with 13lb spring, running no ebc or mbc, hits max at 3500rpm currently. Same turbo.

I thought about that. I have a 14lb spring in the tial wg right now.

My EBC died on dyno and I now have a MBC in its place. It was turned up to 20psi while tuning it.

I believe that the mod I made to the intake manifold is what has caused this.

The HP carries well. I believe the intake mod heped that, but hurt my spool..

I will see how this feels on the track sunday. If it sucks, I will throw on a stock IM and see what happens with the spool. I know it may make the HP dip off, but if I am feathering and clutch kicking all the time, I will take the small loss in power..

Thanks for looking everyone.

I am alive, I no longer own a Miata, so I don't cruise the Miata boards anymore. I've been working my *** off in this Ph.D. program that I am in, so I don't get much time to surf the net at all.

I recently did pick up a new ride, picture below.

I thought you were the owner of the thread, kind of come out of the blue with such post.

Enjoy the overly priced mini.
