Are you sure it's not the reg mate?

maybe...do they tic too?...sounds seems to travel up and down the rail..

or did you mean the hunting?

I've done about all I know how to do now..time for some professional assistance I think

I have been recommended a TD06H-25G with a 12CM housing

There seems to be 2x types of rear wheels on TD06H eg: 11 blade and 12 blade???

Also like the GT35R/TD06H hybrids.

Found this...

GT35R/T04R

Would have change manifold flange to T4

or....

GT35R/TD06H

Then upgrade to bigger housings later like this if needed...

TD06H 12cm

So... some pics of the 25G vs 73HTA compressors and TD06SH vs TD06L2 turbines

And this is what happens when you try to run an SH housing on an L2 turbine

med_gallery_462_50_47822.jpg

The CHRA was made up with the L2 turbine and 73HTA compressor by a turbo shop, so its all balanced and just needs lines connected and bolted up. Well at least thats the plan.

When I have got my current TD06-20G off I will line up all 5 turbos and take good side by side pics and break out the verniers for more accurate measurements.

I have been reading some of my old uni pump design texts and trying to get an understanding of the impact surface finish has on compressor performance. Its interesting that there are documented negatives when deailing with fluids, but harder to quantify for ideal gases. The surface finish of the billet wheel is pretty good, but looking at an EFR 7670 today the EFR turbos have a much higher surface finish. Its probably in the area of around 0.4um going by the materials we use in pharma. So may send the TD05H-18G off for some extrude honing of the compressor wheel to polish it up and see if it makes any difference in performance. Think I found a place in the US that makes billet little nuts for the compressor too so for wank will throw that on after the honing of the compressor wheel. All helps, I want to see if the little 18G can make 260rwks on E85

But my car doesnt run on Trents dyno does it :) Would be interesting to see what my car made on his...higher or lower...but going on the dyno that my car runs on if I make 260 out of a 18G with an 8cm housing then I am doing well,

Interested to see the cars making an easy 260rwkws on 98. Looking at SR20s running T518Zs there arent too many making 260rwkws on pump?!?! 240-250 seems more the norm.

i just had issacs S15 come from racepace where it made 250, it made 239 on mine.. pretty direct comparo i reckon.

    • Is there a way to adjust all of the pedals in an R32 GTS-T? they all sit even, but seem to be a little high for my liking.
    • Lucky man, who owns it in the family? Any pics? 
    • The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p
    • Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.
