is it possible to get 300 bhp+ from lcr with standard turbo?

[jamiebennett81]

corsa and astra vxr's seam to be able to safely run 300bhp from a ko4 dunno if thats effectively a hybrid on them from standard tho?

I thought the VXR's only mapped to around 280bhp?

Easy option is nos! You could get 300bhp from a k04 but it wouldn’t last 5 min as it would be bodged to the eye balls with bleed valves and a funky map. Also to be honest the difference between 280 and 300 on the road is sod all, its only pub bragging rights.

Was you after getting your car to 300 or just want it quicker? If you want it quicker rather than figure related look at things like semi slick tyres, WMI, better mounts or shedding some of the LCR’s chunk

the difference between 275bhp-280 bhp and 300 bhp is very noticeable as my friend keeps showing me in his golf edition 30 his 301bhp mine 275-280 after 2 different dynos an he only has 36lbs more torque an i only have 2 seats and no spare alloy so lightened up a bit an he just pulls away even if i am quicker to 60 he just passes by and keeps going.

well a map may only get 280bhp but if you add fmic or whatever you can get 300bhp out of the ko4

obv this is a youtube video, could be optimistic rollers and this may be a hybrid etc etc but http://www.youtube.com/watch?v=KHSimG1LowI

dunno much about the astras but i know of a guy running 290odd with a standard k04 on his

an FMIC does not directly add BHP, it merely aids cooling and allows for sustained boost by reducing heat soak.

a k04 on an LCR will NOT make 300bhp, it is a complete myth. Dont take what a dyno says as gospel

A well setup hybrid k04 should make a decent 300bhp but a standard k04 cannot flow that much

the average a k04 LCR runs on here is around 270bhp, as a realistic and average figure

there must be some dark witch craft going on to get these k04 powered cars to 300bhp then

and just because other cars that have a k04 get 300 or near it does not mean an LCR with a k04 will too, as the specs of the turbo could be different, turbine wheel, comp housing etc etc

There is a 2 litre engine there, maybe thats why.

+1

forgot about that, yeah what he said

 

[lordgibbness]

Not very likely for the Corsa to make that power though with its 1598cc engine.

 

[Richie-LCR]

really?? i thought the corsa was a 1.6

i did say maybe these turbos are effectively a hybrid did i not? ok a fmic was the wrong thing to say i was merely saying that adding more mods other than a remap could give you 300bhp

 

[lordgibbness]

That is 1.6l lol!

Just to confirm - am I right in saying that a hybrid turbo is effectively one with an oversized compressor bolted on?

slightly more to it than that my friend...

largened turbine inlet
larger turbine wheel
bigger comp housing
360 thrust bearing
uprated oil seals
smoothed inside

amongst a few other bits and bobs, but thats the main part of it

CR Turbos will do this for around £500-700 depending on if you have a k04 to exchange (pending it's in reasonable condition of course)

Ah, well I can't imagine that vauxhall go to this effort on the astra vxr.

I think the reason that vxr's, st's, golf ed30's etc. map to higher power than the lcr must just be down to the larger displacement of the engine...

well technically the turbo might be that

to us it is a hybrid, but to a vauxhall, its a factory standard spec turbo possibly

I dont know what spec a manufacturer considers as standard parts anymore on modern cars in regards to a turbo. I doubt it would have aspects like a 360 degree thrust bearing as this drives the cost up....but know knows!

Can't beleive i missed a thread like this!
How long have LCR's been out, 7 years, and people still claim all these stupid numbers, they've been tried, tested, tried again, blown up, rebuilt, tried again and the still make the same!
300BHP is a joke on a K04 on a LCR.
285 is the most I've seen from a LCR and even that was on generous rollers!

I think the reason the ED30's and Cupra Mk2's make really good power on the K04 is 1. Due to the CC's. 2. Sure i read it had something to do with the turbo and manifold combination.
Someone will prob correct me but hey, thats what experts are for!

i agree with what has been said, exactly jamiebennet81. And front mount intercooler as said doesnt instantly add bhp, it just allows for cooler air and less heat soak, better air flow and maybe hold boost a bit better. Cant really trust any of the rolling road/dyno's they can just be set up and messed with to produce different figures and no idea how accurate they are.. somebody told me the other week they dyno'd standard 225 lcr and the rollers were accurate because one came out 224 and other 226, well i always thought they were 222 bhp anyway so that was a load of made up crap to get you to think " this is an accurate dyno we wont lie about your remap figures".

in most cases the difference between a few bhp and figures arnt how the car feels to drive or puts the power down on the road. a car with less bhp could feel mor driveable and get the power down better than the higher bhp one with rubbish tyres that just keeps spinning.

 

[ibizacupra]

K04 on 2.0tfsi is not the same K04 as on LCR.... apples and pears comparison

 

[maberzee]

that figure on JBS rollers explains it all then

they are always some what optimistic

LOL

sorry something completey different to the thread in hand but noticed in your sig you got glossy black wheels are these standard or did you buy them. and if they are the oem where did you get them done??

 

[turbin]

cost for a hybrid K04 ?

 

[jamiebennett81]

cost for a hybrid K04 ?

as said, about £500-700 pounds depending on an exchange unit and it's in good condition

 

[GREY 225]

Mine made 280hp/300 lb torque on jabba,s rollers and 267hp/320lbs torque on awesomes last year as it is now.
So the power was down on awesomes rollers but the torque was upWho knows.
Dont see much point going for any more power untill limit slip diff is in.
