.. yep you read that right...

Lunar racing have clocked one up to 230bhp:

I guess as it is a race car it may not be the most mild mannered, but even so - i really want to know what the hell they have done to it!

:rofl: - i should not laugh, but i could just not help myself....

Joking aside, i am curious on how it is coming along - i would have thought being motorsport orientated it would have been done by now.... or at least in the shake down phase :)

Well we are getting closer to completion but we are not just building a race car but also complete kits for, if i mentionted we are testing gtb1756vk turbo from a 2.7tdi and also a kkk bv50 from a 3.0tdi and making stainless manifolds and downpipes including oil feeds/returns and developing the mapping so there will be off the shelf kits for different power levels would you guys understand the reason its taking onger than expected.

We are hoping for 230bhp and 350ftlbs with the gtb1756vk and well the figures for the bv50 turbo will be for heavily modified pump and injectors along with forged internals and a huge fmic and 2.4bar of boost for hopefully 300bhp and over 400ftlbs. the car will be done in due course but with a lot of attention surrounding the outcome we want a quality product with a reliable setup, the car needs to be able to compete in 24hr racing so we need to make sure it spot on.

the option for a gtb22060vk kit was in the pipeline but due to it being hard to get enough supply cheap enough for customers we opted for the gtb1756vk and bv50 which are far easier to get hold of and rated at 240bhp max and 310bhp max.

YES! Go on Matt! :trophy:

what type of VNT actuator will these turbos be using, vacuum or electronic? will they work on the facelift OBDII cars?

i'd be happy to see 180hp/280trq :) would the decomp plate be needed for for my goal? or could i get away with dropping to 18:1 for example?

time to get saving and ebay my wastegate GT17 i recon!

the kits are being designed to work with the non facelift models at the moment with the egr control for vnt control, once they are done we will start the long and costly task of working a way round for the face lift models at the moment our only option is to put non obd2 software in the ecu so it doesnt have the fault code issues. A .5mm decompresion plate should take you to 18:1 which should be fine but gain we are only creating the mapping for our setup so it will be unknown how the car will behave on 18:1

Certainly interesting to read about the updates and the two spec's of out the box upgrade you are creating and testing.

full boost would appear to be about standard then, so it would make it better to drive than the stage 2 hybrid in fairness, i will be interested to see the torque curve though.

However that said what is required is quite a step up for most people in order to get it to work effectively - eg this upgrade will require, FMIC clutch, gearbox (diff) head off, belts etc....

You using standard head bolts for this, or gone ARP?

I wait to see how it all pans out... and it might well be a route i follow later on - eg if i blow the HG again and the head needs to come off ;)

Good luck with it though

We are using stock bolts we believe they will be strong enough with low enough emp and compression. Full boost will be 1.8 bar so much higher than standard and expected 350ftlbs the kits are being designed to make a reliable car it's up to other people whether they fit all the mods and how much power they require.
