Hey Guest👍👎 We're looking for reviews of your local CUPRA or SEAT Dealership - it's quick and easy to do: Leave a review now
What exactly is required to take an LCR to 400 BHP
- Thread starter virdi
- Start date
To get the power you would need a 'Hooch' sized turbo, internals uprated, clutch and flywheels upgrade. bigger MAF housing (or aftermarket ECU to get rid of MAF etc) very good CAI supply, big ass FMIC, some sort of BC, tubular exhaust manifold, uprate intake manifold, bigger injectors, fuel pump upgrade, oversized silicon hoses or hard pipe, high flowing head which should be polished and flowed, upgraded engine mounts and DBM, 3" high flow exhaust and race cat.
Then there all the stuff to handle that sort of power and get it to the ground, like coilovers, LSD etc

Theres quite a bit of work to do for this and a few more bits that need added to complete this kit

For a start there is the issue of traction. Our country has shyte weather so on anything other than a dry day you'll be struggling like hell to put the power down.
Secondly there is the issue of reliability. I'd rather go for a 320bhp 'fairly reliable' set up, than a 400bhp 'will it pop a piston today?' set up.
If you are going to go 400bhp you'd have to spend a mint. It's not just the BT & internals but brakes, suspension, bushes, mounts to give you the real benefit of the initial spend. By the time you'd paid out you may as well buy a car with close to 400bhp as standard.

i think traction wise alot can be handled by a good map.
my main concern would be what rev level would the power arrive.. the bigger the turbo the laggier it gets. if the power came in at 4.5k instead of 2.5/3k would it be an enjoyable drive? track car by all means but everyday?
now fit 2 turbos , one ickle one and one huge one and that would be very cool
I'm surprised they are claiming 400BHP from a GT2871R without an equal length manifold, would be tight even with one I would have thought
Of course if you increase capacity, flow the head and get a better inlet manifold then maybe a 2871R could make 400 with decent spool up to boot - but it won't be cheap!
IMHO the Leon chassis is pretty much at its usuable limits with 350 ish and similar torque levels for a ROAD car and personally I wouldn't want anything laggier than I've got now for road use.
anyone seen a backdraft 400bhp kit on a dyno making those figures?
never seen one in the flesh. not dissing, just not seen one or a gt2871r manage these figures yet
re the bhp figures... 400bhp, 500bhp, 600bhp, no fcuk it... 1000bhp.... and the reason for this? Sounds better than 300..something?
fwd.
even when 4wd, with high power comes lazier power delivery. think road car, think flexible power delivery over headline figures, or be prepared to go down the gears to find the power band then rip back up the gears once it all arrives in a big dollop...... woosh, gearchange, woosh, gearchange etc... and think "would I like this?"
When you rush down the road at warp factor one, and just about stop wheel spinning once into 3 figure speeds, if someone has'nt already got in your way, you may realise its very fast, but not as usable as you hoped.
in fwd, will you enjoy it if when the power does come in it simply turns tyres to smoke. think damp/wet weather and consider ALL gears could spin up.
makes for bragging rights, but that about it in practical use.

Yep agree with Bill on his verdict.
When tracking my old valver which was a proper 200bhp MK2 who many will remember you could use and deploy every ounce of power courtesy of a slip diff but in the wet even with just a paltry 200bhp and 160lbs it commanded respect but as an all round budget package it was pretty good value and held very respectable lap times.
My MKIV was really good with APR mapping initially with some Koni's but as the track beckoned I then had to invest further with the introduction of a FMIC due to heat soak big brake upgrade as standard brakes on track were wanting together with ARB's Quaiffe differential clutch flywheel etc.....you need all of these items plus poly bushing to get a MKIV half decent for track....add that little lot up and it's quite a bit.
Going big turbo was a choice I made as I came to a cross roads on whether to keep the car or buy something else. Looking at what I had invested I decided to be the guniea pig when Awesome put the APR Stage 3+ kit on.
For what I spent I could probably have had more grunt going DIY and cobbling together a bigger turbo and the associated injectors custom manifold but it would be pretty close time you add in the mapping.
At the same time you have to factor in proven reliabilty but also the everyday drive of the car. Even with the APR kit it's more laggy than K03 s but it's actually a better delivery and it's really on song at 3k which is nice for a road car and it pulls well into 7k territory. A car that only get's going from 3500-4000 as a road car is a pain and can actually slower and laggier out of corners.
I drove a car a couple of years ago which was a case of wait wait wait wosh all hell let loose wheelspin all over the place being FWD(from 4k then change wosh change wosh a horrible road experience )
Even with my car and spec it needs great respect to temper the delivery....driving it smoothly deliver's more speed...scruff of the neck down changing = wheelspin!
Wet weather is nanny approach or wrecked tyres and a low life expectancy on transmission components.
Glad I did convert mine now though as it's registered Feb 01 what with the new road tax rates looming.....still cheaper than buying a 340bhp vehicle out of the box too.

Wise words from Mr Bill ![[B)]](/forums/styles/seatcupra/oldforumsmileys/shades.gif "Cool [B)]")
The benefits are much more related to how the power is delivered rather than how much, and you will get much more benefit from less, mapped to deliver in a smooth fashion IMO.
Unless you do some serious mods to attack the traction issues, 250bhp is enough in fwd to be a pain in the a$$ unless you can have a word with the fella upstairs to guarantee it never rains and then the council to make sure the roads are always flat
