My 30DET is now running TDO6H 25G, budget build with Hybrid manifold and 50mm Turbosmart gate. Turbine is the 11 blade option with 12cm housing. Tighe camshafts correctly dialled. Track car, chasin

My car blows fireballs the size of a car so i dont think its running lean, :yes:

I backed the boost off to around 16psi from 22 to control the heat, it was stupid hot at winton this weekend. It did make a difference, as it should.

Very low timing will result in excessive exhaust heat. It will cause the thing to run really hot, ping earlier than it should when trying to run more boost (capping power) and will also make it get on boost quicker.

I have had a setup tuned like this and am speaking from experience. The car got on boost fine and when/where expected (if not earlier) but the power delivery wasnt right.

No cat, does have a straight through muffler and a res though,

The AFR's were a little rich on the dyno, not heaps just a little to be safe, from memory they were around low 12's high 11's i think. I'm pretty tired from the weekend, i could be wrong i will check later today gonna go see my tuner.

Then yeah could also be timing as above

When you say low timing to you mean advanced or retarded?

The car had around 40-50 on the knock. Nothing drastic.

My car had numbers lower than 10. The tuner couldnt dial in more because the boost was too high straight off the actuator. If we had a lower pressure actuator it would have been a different story.

Is this hitting any points with your setup? whats the lowest boost you can run and did your tuner go all out on the tune with low boost first?

My understanding is the best way to tune works like this: Start with the lowest boost possible and most aggressive tune, slowly wind the boost in and soften the tune as you go.

Rather than get fueling right then add boost and slowly add timing - doesnt work.

I don't think my timing was any lower than 10. Pretty certain it was all higher than 10

We didn't completely reset the boost. Lowered it too around 14psi and went from there. I blew the gearbox on the weekend so once I get it back together, next year, we'll put it back on the dyno to check it again before I buy another 3540 and sell the Kando.

Not giving up yet, i wanna get back on the dyno and have a little more of a play, but i dont think that will change when the turbo spools up and starts running out of legs.

out of curiousity what turbo are you running? what size rear? how much power are you making?

Mook what state are you in? Maybe send your rear housing to Stao (Hypergear) and see if says theres a problem with it.

He stocks these turbos too at the moment. He will be able to directly compare yours to one of his 10cm's and also be able to check for defects. If its not right he can supply you the new housing.

I'm in Victoria, Hypergear is in too melb isnt he?

I'll be able to go see him first, that way i might use a little less time playing on the dyno.

FROSTY, I was a bit disappointed when we tuned it, though its not so much about how much power it made as when and how its making it, very early and seems to run out of legs at high revs, let alone the heat issue.

      Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...

      WGNC34 Rear springs

      By zoomzoom · Posted

      It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
