So it went on the dyno today. Seems to be all good and safe. It made 242rwhp at 11psi. In 5th gear.
I took some video, but it's dodgy.

242hp on 11psi on pump gas?
I'd love to see that timing map.

What kind of dyno is it? That figure seems quite high!

Lightyear has a custom downpipe that eliminates the "pinch" after the flange that exists on the OEM (and FM) downpipe, but even with that, I'd expect it to max out around 200-210hp with the IHI turbo at 11psi.

So what's your "secret sauce"?

I was surprised myself. At the end if the day, it doesn't matter what the hp is. As long as it does quick lap times, and stays together.
Gearing may contribute to high hp. The first pull was in 4th. Made 200kw. Next pull I asked for him to use 5th 1:1. Came up 181kw.
It does feel fast. Maybe I can take on a straight track and test the 1/4 mile time. Will verify dyno reading I guess.

I was not expecting to even get 200hp. So I was in disbelief myself.

The combo is-

2001 MX5 with VVT. MS3 ecu. MSM manifold, turbo and elbow. (I did spend a little bit of time porting any areas that looked like they needed attention.)
Straight thru 2.25" exhaust with high flow cat. Pod filter, ebay intercooler (that works really well by the look of it), short pipe work. 6 speed and 4.1 Torsen.
I think that's it.

VVT is fairly unique to an IHI setup, I'd say that would help a bit. Plus you car would come standard with a flat top manifold.

Perhaps it's the flattop, because those numbers are indeed quite high.
Yeah quarter mile trap speed would be able to confirm that.

Either way I'm sure it's a fun setup, congrats.

Would be good if I can find out how to get race chrono to do 1/4 mile time and speed. It must be capable.

I did download some 0-60 and 1/4 mile apps. But have not used them yet.

Went to a short-ish track with lots of elevation changes. Came first outright against 74 entrants. Lot of race cars with full race slicks, and lots of $$$$ spent on them. So the car is showing potential. I was nearly 2 seconds faster than the next best competitor.

The car would start to get high in water temps after a few laps. Oil cooler might be enough to fix that. Car over steered too much, and brakes need ducting. But it all worked, and nothing broke, so a good day.

I used my phone to video the laptop. So it's not the best. And I put the wrong year in the title. Wonder if I can edit it??

Very interesting course. And props for your driving, I think I would have thrown the car into the landscape very soon...

It is actually a motorcycle track. In recent years they let cars use the track. It is very exciting with the elevation changes and off camber corners. You can't see around some corners until you crest them.
I will be doing the Nurburgring in a few weeks. A little longer than this track.

On another note, here is my other car. It came from California. I need to import a new interior kit for it, and get it on club registration. Then go cruising. Be nice to listen to the V8 motor. Anything has to sound better than a Miata...

I went to Europe for a few weeks, so didn't get much car stuff done. I did get to drive on the Nurburgring and Monza.
Last weekend I took the car to Phillip Island. I got the meatball flag after one lap. There is a lot of oil coming out of the breather hole on the rocker cover. I made a hose with a T go from the rocker cover to the sump, and off the T to an air filter. But all the oil was coming out the little air filter.
So I put a large temporary catch can in. It helped, but still got oil everywhere. The car also gets too hot after a lap or so.
So the idea is to open the grille opening back to full size, put in an alloy radiator and make new ducting. Then make a real good catch can with baffles and a return drain.
I managed 2 laps at full speed, it was enough to win my class, and put me in 4th from 122 competitors. So that was good. But it would be good to see what it can do with some more practice, and some fine tuning of the set up.

I have widened the radiator opening, made a nice big duct, fully sealed. And made an airbox for it too. And my mechanic made a custom catch can for it. I am booked in at a local track (Sandown) on the 29th, and Phillip Island on the 13th. Can't wait...

The fastback mould is now made. By tomorrow lunch it will be ready to use.

Pic of the trunk moulds for the fastback, a fibreglass hardtop, and a vacuum infused carbon fibre hardtop.

This is what it looks like now in road spec. Have to drive with no roof until I finish the fastback.
