L-series with over 200bhp already created...

.. yep you read that right...

Lunar racing have clocked one up to 230bhp:
Be part of the ZS 24hr team

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!

sounds interesting.

No details though?

edit: according to the website the engine was fitted yesterday. No mod details?

I'm willing to bet the torque figure isn't particularly impressive. For that power to be made it's got to be all up top surely...

nope fraid not....

the thing that is slightly confusing, is that the car LR1a appears to be identical to the ones that vulcan racing use (paint job only) - who have split from lunar racing this year. or they have not split but formed a seperate group i am not sure which - on the forums one of the people is car13....

Even so... i want to know what they have done to get 230 out the trusty L-series

Be interesting too because their blog from a couple of days ago quotes them aiming for 200bhp and 300nm.... (220lbft) - unless they muddled up their units.

Personally I'm suspecting the 230 to be a target figure and a sign of things to come?

Either way, day before yesterday the car in question was a 2.5 k series.

I just can't see any development 'stress' on their website unless it's all been kept under wraps.

yeah had just dug that out.

220lbsft was what mine was peaking at when it had the wingy's in.

but it is the same figure as what mine kicks out at 4000rpm still....

my guess is that it is a big snail bolted on so it is all top end.... wonder if they will get head lift issues with it

Well we'l see.

I think "we'l see" pretty much sums this thread up. I don't want to sound like the cynic but unless they are a wonder garage, 2 days is a very short time to get an engine fitted, tuned up and dynoed...

I'm going to suggest that the 200bhp hasn't been broken yet, but there's another person with a fair budget trying

edit: I assume they got the units wrong. 300nm @ redline is approx 160bhp. 300lbft puts you just across the 200 mark.

Can a gasser tuner switch to diesel and do the work of the diesel section and beyond in a very short period of time? Interesting question.

yes that is one slight downside of things.. unless they have already done the work on the engine pror to dropping it in of course....

even so - we will see is spot on i think.....

i dont think we would have any smoke issues with summit that size tho - if you got it to spool that is..... I wouldn't want to to be anywhere near that thing tho when it is spinning.. the air generated would be pretty heft y i would imagine!

I think it is there to stop small animals and children being sucked in rather than do any actual filtering

Think it's possible just how much money you can chuck at it, internals bigger turbo very top heavy lag not an issue on the track.
Sounds like they built it before putting it in so a couple of days seems ok to me.
That leda suspension looks good on the build photos though.

Been thinking of a huge turbo myself not that big like above but something much bigger than my hybrid, then adding some form of lpg/nos anitlag but also watching a few superchargers at the moment too.

lets not get too excited, the ZS BTCC cars had a 2litre Kv6 running 370bhp.

Just cos it's physically possibly, doesn't mean it's a good idea, especially in a roadcar...

that said i would like to know what they have done to it - the figures suggest a turbo upgrade that spools late, as the torque is pretty low in fairness...

but is that all they have done - considering it needs to be thrashed for 24hrs i would have thought more than that would have been done.

Also what about the injectors and the mapping - just SDI's or a 'better' race spec than the wingy's etc etc etc

I don't know.

Even if the torque they quoted was in lbft, the simple math is, unless they've got power at 5000rpm, their quoted torque doesn't make 230hp until, well, past redline.

Don't want to sound too critical like I say, but the torque peak should be just as the turbo hits it's happy zone, so it's looking like the turbos so late spooling it just gets going at redline LOL.

Be interesting if they have done it, just can't see how it fits together yet.

Looks good, would be interesting to see some specs. Like said above it doesn't take that big a turbo to achieve those figures, I'm sure kris will be cable of those figures when the car is up and running.
