Mad's car is an auto mate.
Mart.
Yep it is auto, am gonna test once and for all the strength of the autos.. Have done a recent amsoil flush, and oil cooler has been installed. If auto fails I will rebuild and strengthen it up.
Is there any chance you would mind fitting an oil pressure gauge to the box somewhere? I'd be interested to know what sort of pressures you see.
Sure, but I got no idea how to do it? I used the 'how to install a boost gauge', is there something similar?
Just need to "Tee" a pressure gauge into one of the lines going to the transmission cooler: that should be sufficient, as the whole system will be running at a constant pressure.
Any news??
Mart.
Almost done, manifold goes on today, top cooler pipes and then start her up and a quick tune and dyno run.
Pics are:
1- rear turbo, basically done.
2- Front turbo, waiting re-locate oil filter, very fiddly job.
3- Custom front engine mount pic also
I'd get rid of that pod filter sharpish if I were you.
Apart from that it looks tip-top!
I'm not sure I would: the standard airbox is going to start being a limitation with turbos this size, as is the inlet pipework, and possibly the MAF.
As it'll need a complete remap to run these properly, the MAF isn't much of an issue, as it can either run with a bypass pipe, or simply be fitted into a larger diameter pipe and rescaled. I would be keen to locate the huge pod filter into the wing somewhere, or into a cold-air box, but that can come AFTER it's up and running
Madhav still has the maf at this stage, but with a full ecu and tuning having a pod filter doesn't matter, you can tune around it
well, that's not strictly true: The main drawbacks with pod filters seem to be MAF innacuracy and heatsoak.
You can't map around heatsoak, but then with the amount these will flow, it's less of an issue.
MAF innacuracy can be a problem regardless of ECU, however. If they airflow distortion pattern is linear, then, yes, just correct the MAF scaling and the problem is solved. However, typically, the innacuracy is down to inlet side turbulence, which can mean varying different air-speeds at different rates of flow, in some instances causing the MAF to underread. The best fix for this is generally to move the MAF away from the filter: a 25cm piece of pipework should be more than sufficient to achieve this.
Also beware of locating the MAF too close to the turbo inletts....not a problem on VR-4s as the y-shaped split for the twins breaks down any vortex created by the impeller, however on a single turbo system it's benficial to have a stable airspace between the turbo and the MAF, either a bend with pipe either side, or an insert in the duct.
I got a cold air intake, flows from the front, to the right of the grill, up through a pipe, and ends up right under where the battery used to sit, i.e. where the pod is. Will also put a bonnet vent just on top of this, and notice there is a piece of steel there acting as a kind of heat shield... all these combined should provide ample cool air.
hi Mad,
Any updates, you got her running yet? As I said before, I'd like to order the upgrade kit or as much as possible from your guy. Could you find out how much it would be and parts it will include?
Cheers,
Mart
Hey dude, what are the specs on the turbo ?? what's the turbin side and whats the compressor side specs
Hi mart. It's done, as far as i know wayne was just checking for leaks, will check tomorrow. It was quite a process, a lot of trial and error. Will get a tune etc and if all is good will let u know about what exactly is needed for the upgrade and what Wayne can make up and what it will cost etc..
Mr Salas, check the start of the thread, each turbo is good for about 280hp.

KKR 280 spool up time, 3rd gear going up a steep hill applying very light throttle.

Overall I can say I am very impressed with the spool up time, although I still haven't opened it up at all and have to drive like a granny till it's tuned on Monday.

Wicked - congrats mate and big respect for taking the trouble to do it right.
I will be first in line to do this next if all works out!
Keep us updated on tuning.
Mart.
Engine bay looking very nice.....Y pipe is a bit of a bodge, but it still looks cool: your mechanic obviously likes attention to detail on a budget.
Can't view video from work, but very interested in costs if the spool is okay.
Not sure how these stack up against TD04's though - suspect they're cheaper and not that big a compromise on spool.......ohh very exciting!
Spool is good considering how much power these turbos can make. I mean I can't give it much throttle at all cause it's not tuned and obviously detonation could destroy all the effort, so I'm gonna have to wait till Monday for a tune, but in it's current state at 1/4 throttle, it hits 5psi by just under 3000rpm, and 10psi by 3600rpm.... so not bad in comparison to the standard turbos. Will see when it's tuned with the dyno readout how it looks on Monday.
Looks and sounds good, now start cranking it up
