I've entered a roll racing event at the Sydney Motorsport Park this coming Friday but the weather predictions aren't too good for that night.

I've fitted up my Mickey Thompson ET Streets for the event on some 18x9 Simmons OM wheels, they a 2454/40x18. Took it it for a kebab run the other night, they are hooking up nicely even though they have been sitting next to my garage unused for about 5 years
Looks good, Steve 👍

Hi

I've been talking to my local Subaru tuner and AWD Subarus with similar specification motors to mine are making 360 - 380 kW at all four wheels.

I've been thinking that there must be a restriction somewhere in my setup, I'm running a Varex muffler and a water to air intercooler.

My ECU has an exhaust pressure map sensor so the other night my son and I did some extensiveness testing.

So 290kpa inlet, 350kpa exhaust On 25psi (eboost), so 1:1.2 which is quite acceptable.

We also checked pressure drop across the intercooler which was about 3 psi.

So now that I'm confident that my setup is not causing issues I'm going back for a touchup tune with some more timing and boost as suggested by the Subaru tuner.

Steve

Fitted up my track wheels with Toyo R888R on them to see how they would look. They are genuine hollow spoke 7.5x18 50 ET and 18x8 52ET

Thanks.

They are local XY Ford Falcon mirrors that I modified to fit, they look cool but are a bit small. A link to a local website that sells them https://www.fordmuscleparts.com.au/s...keyword=mirror

I cut the bolt on base off and and had it welded up and I used the the stubs from VW mirrors so that I didn't need to drill any extra holes.

The people standing with my car, are me and Dinos son Valentino, then Dino who is a member on here and another friend of mine Barry.

I organise a VW cruise on the 1st Friday of the month (Der Erste Freitag) at Harry's Cafe De Wheels

Hi

Another day another dyno run

This was on a hub dyno, same tune that made 319 rwkWon rollers made 350 rwkW on the hub, difference being no wheelspin. The dyno operator confirmed cars that don't wheelspin make just about identical power on both his Mainline dynos

The dyno guy didn't have 5x130 hub flanges so I bought these 130 to 114.3 adaptors from eBay

Nice results again!
At what boost pressures are those lines? Green line is 14,7psi or so?

He's missing out a lot of work not being able to dyno 5x130 haha!

Low boost was about 22psi.

interesting point, same tune that was on rollers made 319 and on the hub 350, so just 1 psi of boost and more timing it made 32 rwkW more.

The waste gate is fully closed now at 31 psi so out of turbo which is what I wanted to achieve

I've been running 245/40 x 18 Mickey Thompson ET streets, these were 2nd hand and pretty old and the side walls don't have a lot of give.

A local speed shop had a special on some M&H 245/55 x 15 drag radials.

There was no 15 inch Porsche factory wheel that would work because my wheel bolt face is pushed out a long way by my 944 trailing arms so I had a pair of 15x6 Cookie cutters widened on the inside to 8.25 inch to take these tyres. They worked out at ET 65.

My local tyre guy did a finger balance rather than a cone balance for me
