The 1.2 bar chip is produces ~215hp with 93 octane and a stock exhaust. What would the hp gain be at with a 1.5 bar chip? The 1.5 bar chip requires a 60mm exhaust and does not carry a warranty. TIA

Before you get excited about the 1.5 Bar, you have to remember, a chip causes everything around the engine to work harder, faster and longer than it was meant to.

If you try to go from a stock ECU or even a 1.0 Bar chip (that you've been pushing hard) to a 1.5, pretty soon you're going to be having a problem with parts around the engine, if not the engine itself.

Also, the Garret 1.2 Bar chip is the 212-217 bhp and roughly dyno'ed about 200 to the wheels. Granted, it may sound fun with more boost, just make sure you have the parts in place to handle it.

what year car do you have? and what does neuspeed say you should have to run that boost, and remember audiboy my X chip runs that high.

skabaru

are you sure about that? with the commonly accepted 23% driveline loss, you are looking at ~246 hp at the crank...

so... yeah... not really...

the k03 efficieny point is about 15psi... maybe 17-18 on the 2001 sport ko3 thing... hence the x chip and the apr 01 chips pushing more at the crank than the nDBW...

If you push it that high and hard all the time, you're bound to cause yourself problems.

skabaru

compared to not chipping? yeah...

compared to driving with 7psi at half throttle? sure...

but running an xchip all day isn't gonna make a huge difference... you aren't talking 150,000 on one engine and 75,000 on the other....

the difference is negligable...

I am not arguing that more boost will lower your engines life. I am argueing it isn't gonna make a huge difference on a well maintained engine.

200 is not even what the K04's put out at the wheels. 215 at the crank is about 160 at the wheels not 200. To make 200 at the wheels your going to need to make 250 at the crank which is not easy to do with a K03 unless your pushing 20+ psi on 104 octane, I should know since that is the amount of power my K03 setup made on 104 octane running 14.290 at 97 mph in 100+ deg temps. Other then that there is no way to make 200 at the wheels with a K03.

On pump gas it will never go above 225 hp with the K03.

170 is the engine power right?

X-Chip is between a 1.2-1.5 Bar for boost under circumstances that I've seen. I've seen 20-22 PSI on a few cars up in Seattle about 6mon-1yr ago. (granted they were k04 not k03's) As far as Octane goes, I've seen 93-100 Octane used with dyno's at achievable 200HP or near. One car was FWD and the rest Quattro's.

So, in theory and this is just based off what I've witnessed in person, the 170HP + X-chip ='s what.... 210HP in theory. At best with a aftermarket bpv, FMIC and from the cars I've seen an true cold air intake, getting around 200HP is possible but the hoops you have to have your car jump through are painstaking.

Also getting back to the original topic, the Neuspeed from what I've heard doesn't handle the boost as efficently as the Garret chip does.

only makes just under 140 hp at the wheels. I haev seen 2001's with K04's running 27psi and still only making 235 hp. Running high boost on a K03 only gets you higher tq not really higher hp since boost drops off so fast with the K03.

BTW my car is a 150 hp stock that made 200+ at the wheels on a K03 race chip, 225-250 hp at the wheels on street/race chips for the PES T28 kit and then made 180-190's at the wheels on a K04 running 14.5-18psi on my 2 liter motor on a standard K04 chip running 91 octane. Believe me when I say I have had my share of time on different dyno's.
