He modded his 1.8T to 375hp? Damn.
Ok well to clear things up....It's really not that hard. Start with a moderately sized turbo upgrade..i.e. GT28RS and add proper fueling such as 830cc injectors, plus a dash of 3" exhaust. Then garnish nicely with Eurodyne Maestro7 software and a spiffy front mount. Bingo you now have waaaayy more horsepower than you will ever need.
The car started life as a 180hp stock GTI, around 2003 it recieved a APR stage 3 kit which I installed for the prev owner. I had the chance to buy the car last year in need of a new turbo. At that time we decided since the car was a full APR car we'd just continue and go to Stage 3+ from stage 3. So 3 grand lighter in the wallet we had her back to her former glory....at this point car was roughly 300hp on 100 octane.
The car just never drove "well" it always had very poor drive-ability issues from day one of the upgrade. I went back and forth with APR and got no where with them. I had finally had enough of all their smoke and mirror crap and we switched to better engine management. I researched my decision for months and finally after bugging the crap out of Chris@Eurodyne we went with their software and tuning package. This meant I had to change fueling...again. I had a few choices and we decided with 630cc injectors and his very well written base file. Car now runs amazing...so smooth and drivable its like driving an Apple car if they had one. On my never ending quest for more ponies I picked up a set of 830CC injectors and am in the middle of procuring a water methanol set up to keep things on the safe side.
It is extremely easy to pull huge horsepower gains from one of these cars...just takes small cash injections at regular intervals
All HP figures where done on 100 oct fuel. You have to figure, as a rough estimate you will lose about 40hp on street gas. The only limit is the rods and pistons....soon as we grenade it I'm going to address that issue with some JE pistons and Integrated Engineering rods.
As for R32's....nice car but sooooo anemic on power. The 3.2 VR only puts down maybe 200 whp...yeah I know the specs are around 250 but with all the scavenging from the all wheel drive you lose a ton of ponies. They have a ton of torque so they feel a lot more powerful than they really are. I quantify that car as more of a Grand Touring type car not a Sports car. It also takes a ton of money to upgrade those to put real HP down .
Soon as we get her to the dyno I can post up some runs for ya....however it may be a while till I get all the tuning worked out to the point I am happy with it.Oh and best part is we still get around 30mpg highway if I can keep my foot out of it..LOL
