The msm was supposed to be built before I got it but circumstances means it will have a tubular manifold 3" exhaust and EFR on 12 psi first.

Update. The white na6 has its much taller wing mounts and braces, water leak fixed, vacuum lines and boost controller done and it's been driven.

It's running heaps lean so that's great news, it barely even drives once warm up enrichment has stopped. Obviously it wasn't driven hard when lean.

New crusher style front bar flat floor and splitter early next week tune late next week.

Got a link to FMs tests?

Heres what you're missing, to make the same power as an efr you'll need a 3071 or maybe even 35something Now compare spool data.. the efr will blow the GT out of the water. This is what they mean by "spools like a 2560 yet makes the power of a 3071". Bigger turbos make more power since at peak power they are in their efficiency ranges however because they are bigger turbos they suffer in spool. The EFR on the other hand spools sooner. So technically it is apples to apples.

I may be a few days late but nice work on the exhaust, fit and finish are fantastic!

You know what 18psi, you need to grow up a little, I was responding to a specific post where a question was asked about something i said and being as clear as possible in order to avoid some jerk going off because I wasn't clear.

Jimj
There you go speaking out of your butt again. Get your facts straight: I don't bash garrett. In fact, I'm one of the very few that doesn't completely discount garrett even to this day, while many have basically written it off as an "inferior product". I have a garrett 2860rs currently.

Stop posting and start reading. I promise you if you DON'T come into a conversation completely clueless then start arguing with everyone because you were either un-clear originally, or plain re-gurgitating known basics or arguing irrelevant info, I WILL NOT be "mean" to you and cause your panties to wad up.

Seriously. Just so you stop crying here's a +1 rep

One thing I think is an advantage is a simpler downpipe connection on the EFR, but again is it worth the money?
What are you talking about? the car this thread is about has a built motor. the MSM has a stock motor. He is not worried about breaking the built motor with the EFR on 12 psi, he's wondering out loud if the torque from an EFR at 12 psi will break the stock MSM engine.

What are you even talking about man?? the 700 rpm spool advantage was over a 2860, which NOBODY was talking about until you mentioned it a few posts back saying it's more comparable to an EFR than the 2560. You brought it up, then you're saying he won't see 700 rpm spool difference compared to the 2560. Nobody said he would see spool 700 rpm sooner with an EFR than a 2560. That comment was in response to your left-field comment about the 2860.

Please stop bringing irrelevant crap into the thread. thank you.

This would have been a lot simpler if EFR made turbos with similar power goals as say a 2560.

Lol what's the point.

Here's another question, what's the most powerful (peak) road course miata around. Andrews black car is around 360whp right? When this has an ear it will be able to make 400, I imagine gearboxes are the main issue.

In Australia the main specialist miata shop says that miata go quicker at 180rwkw than 220rwkw. All I hear is "I cannot be bothered to engineer a traction and/or drive ability solution".

With 17x10 slicks and ms2's ebc setup nice with a nice responsive EFR I hope that 250+rwkw is drivable and quicker than 200rwkw.

And if not, you call up racelogic and buy a traction control system.

impossible a car with 240rwhp would be faster.


that's why soviet wont race me. I'm making 240rwhp and he's making ~400rwhp.

I said quicker not faster.

The issue we have had so far is that the throttle is non linear, thats what I feel the issue is anyway.

With the ms2 ebc I hope that it will be linear enough to make good of the power rather than just be tail happy.

I have pics of the temporary test wing mounts also, wanna see?
