"Most specific torque (torque per unit displacement)
The mean effective pressure (MEP) is a useful comparison tool, giving the average cylinder pressure exerted on the piston.

Have you ever driven a FWD car with anywhere near 260whp? It is a blast to be able to roast your tires at will. Now more power is always better as long as it's useable but I dont think I would really gain anything on the street with that much more power. My goal was to make the car a fast daily driver that would outrun alot of cars on the road.
Just a bull**** flag comes up for me, especially now that you're saying you did bottom end work and head work and only made 260 wheel on a 2860.
260whp is really not a lot considering how many in house high performance cars there are straight out of the factory that would easily stomp on that power figure.
YouTube - Volkswagen GTI with GT28RS Turbo PES Tuning (15% fwd drivetrain loss on his 380chp is 323whp..)
This guy has a 28RS (Aka 2860) and somehow he made more power than your car on a 'built motor'.. Doesn't make any sense to me. For the claimed 8 grand you have a setup like mine. Which is a fully built bottom end with forged rods, decked and rehoned surfaces. Forged pistons. Built head, valves, retainers and springs all done, entire head refreshed. That and a massive HTA 3076r .70 A/R. Not to mentioned a much much larger parts list for fueling and fabrication.
lol more conveniently a 28rs racing a bolt on WRX!

I dont mean to bust your balls just facts arent adding up over here. A decent 28RS setup wont run more than 4500-5k.
one of my close friends has a 2008 A4 with a TBE and tune...My 06 wrx has a catback and it is pretty even with me having a slight edge...we race alot and bu1lsh1t about our cars a lot because they are pretty even...our other close friend has a 2004 b6 s4 and from a dig it is pretty even with us too until about 85-90mph, then he walks away
I love how this thread has kept going
My friend with the B5 2000 S4 came off a Jetta VR6 that he wanted to turbo but ended up saying screw it and got the S4 instead. Probably better in the long run as far as power goes...
But I know the VR6 can be wicked fast. Not a fair race against a WRX I don't think. 6cyl vs 4cyl, both turbo...hmm.... wonder who's gonna win that one...
But anyways, I guess I'll let you two continue to battle this one out. Militant Grunt, what do you have again, a built A4?
haha i just realized that i said the same thing in the second post on this thread...hhahhaahha
I fully agree. There are way too many variations and technologies involved in different engines, and they're constantly improving efficiencies. As far as basic theory goes though, Torque is built with displacement.
As we see all of these new technologies such as direct injection, variable valve control systems, variable geometry forced induction, sequential forced induction, etc... There are going to be engines with different efficiency levels, but no matter what... with the same specific technology between two engines, torque will be built with stroke volume and compression.
An Evo comes with around 230-240whp straight from the factory; an STi with around 250whp; a mustang GT with around 240whp i believe...
How many cars for that price range are just as fast as those cars for the same year...
A g37 puts down about 280whp and weighs like 3500-3700 lbs
A g37 will not "stomp" on either an EVO or an STi.....and not a mustang gt either
If you are talking about porsches and ferraris; then not even a 330whp audi will take a 350hp porsche 997S

Ok, what performance car "out of the box" comes with the 260whp? I cannot think of one in the same category as the gti. The Dodge str4 would be about the closest right?
+1 and someone jump in here and stop me but... the A4's tranny and drivetrain would start to crumble once you started pushing past 260whp, no?
Hell, I know our WRX's can't take much more than close to 300whp or just over before they start to have issues, right?
Kevin, you put down 294whp, didn't you say if you put much more down you'd have to be looking at a 6spd tranny?
The car didn't handle the 260hp that it made, let alone any more. After first gear decided to grenade itself I had the transmition rebuilt and had a Neuspeed clutch system installed. I was also warned by the guy that did my tranny that I would brake other driveline parts if i wasn't careful and that I shouldn't over abuse the transmition even after it was rebuilt.
