looking at the power of the audis out thre 300bhp seems normal how is this arrived at ? i’ve looked at tuning companies that upgrade the 1.8t engine and most seem to only upgrade to 270bhp are people spending buckets of cash to get the extra 30?
Someone might post a more technical response but have a look at auto-teknix.
They are the main (if not only) company offering this conversion for Loti
The power of the 225 BHP engines can be increased to about 270 with remapping and fitting of a free flowing exhaust and intake system and an intercooler upgrade. However, the small turbo has its peak torque at about 3500 rpm and it falls off from there. The turbo used on the 300 BHP conversion makes peak torque at about 4300 rpm but holds that torque much higher in the rev range so the area under the curve is greatly increased. The gain in performance is much more that just a 30 BHP increase implies.

thanks guys going from 190 (on a good day!)to 270bhp the car is hardly going to be slow i can only image what the extra 30 would feal like…should only be availabe to men fron NASA !!
imagine what 350 hp will feel like
Yeh but you wont be able to control it Dave, you better get a few spare clams ready
clams at the ready
Have a look at our site to give you an idea of relatively standard spec engine gains with just software, or bolt-ons (stage2)…
As Bernard says the standard K04 turbo runs out towards the higher revs, more efficient cooling helps this but they tend to see quite high EGTs when pushed hard up the rev range. Easy 270 peak though with decent torque throughout the range, run it on lower boost at low rpm to reduce heatsoak and high EGTs at the top… more progressive than aggressive which would be better suited to the Exige. The lower spec engines are as good a starting point if you’re going to change the internals, turbo and manifolds anyway. I guess 5 or 6speed box is your call, 5speed is smaller and easier to come by but has lazier ratios.
Most of the conversions seem use different turbos from standard which tend to be better suited for higher (than stock VAG) revving engines (along with the relavent internal upgrades).
IHI or Garrett turbos are the most commonally used, in a variation of sizes and housing. VF34 or GT28RS normally.

440bhp from a std VAG engine ?
Hello Kev. how you doing mate?
I was speaking with Mitch just teh other week about your new toy/project…Bout bloody time you got a proper car… .
see you again v.soon no doubt.

Hi Kev
I heard a rumour round at Guglielmi’s that you had bought or were buying an Elise. Is this true ?
You need to come out for a blast in my Audi car sometime, give me a call at Gug’s.
And I need to talk to you about ECU’s etc.
Bernard
440bhp from a std VAG engine ?
Yup, but you are pushing your luck at that. Probably OK for 1/4 mile blasts but it wouldn’t like too many trackdays. You need to change the rods at least to get them to hang together for long at that power.

Bernard
And your pants no doubt as they wouldnt hang toghether for too long either…
So says the man that’s hard enough to drive under Astons.

I had nothing but a a pair of shorts on under my race suit that day Ian… i.e. Plenty of room to expand!!
