KO4 Turbo review

[Plautos]

without sounding like a complete idiot ,what does egt stand for?

Exhaust gas temperature.

[mikepologti]

ahhh ok cheers

Lol - for the third time : YES within the specifications handed down by the OEM's & equipment manufacturers.

What is your EGT strategy?

Ok so your saying that your EGT's are stock or close to it .

What is the optimum a/f ratio for a mk4 gti Golf to retain these standard EGT's on an Oettinger chip ?

[Bug_racer]

I do not understand this fight about EGT's.

I believe once we give more power to the engine it will raise the EGT anyway.

I think we should get worried when something melts, sparkplugs and the turbo shaft for example or if we have loss of power at extreme conditions. I’m using NGK number 9 and pushing all the fuel I can, to get the EGT as low as possible.

EGT's and lambda are probably the most critical tuning sensors things that need to be looked at to determine a correct tune . Too high you melt pistons / damage rings . Too low and you'll never reach the turbo's true potential .

The heat range of a plug is pretty important as well , including the gap in trying to maintain stable egt's

what will a ko4 polo gti with downpipe do 0-100 please

[Bug_racer]

What supporting modifications ?

what will a ko4 polo gti with downpipe do 0-100 please

My guess is 6.xx seconds, with traction once again being an issue.

[vwthunder]

Guessing 0-100 times wouldnt be very good, due to wheelspin and 1st gear being a waste of time, 2nd gear is when a polo really shines

Even with a K03 first gear is very wheel spinny

0-100 times are only good for red light racers. even a chipped K03S has torque that comes on like a ton of bricks, which is where it matters.

[pig]

anyone that actually has a ko4 with just down pipe 0-100 would be great

[noone]

Why are you asking Pig? We Polo boys don't spend a lot of time looking at 0-100 times, etc.

Personally, I don't see the point in the Ko4. I'm sticking with the K03s or going Garrett.

The 0-100 times would be horrid TBH unless the traction is fixed. With bushes coilovers and front sway, much more traction is available.

0-100 times for the K03s should be in the hi 6's with the right mods and low 6's with the K04, but it does not add a lot of power.

Are you still having traction issues in first VWThunder? I would have thought the KW's would have largely fixed any traction issues you may have had.

I guess I havent really tried to do a good launch

It looks really stupid if you try to take someone at the lights and the tyres do their little squeal thing

[instigator]

5.5 sec is my goal when i have a remap.
but for a FWD car with road tires thats about the max.
i guess whith semi slicks a low 5sec can be done 0-60.

i think the polo is verry strong in 1st gear also.
most of the time i have a good launch.
this wheek i'll post new movies from today's dragrace @ Zolder.
but thats something else

i bet a polo with K04 is wicked fast!

[Petrina Polo]

I used to own one of these cars.. trust me, dont go the K04 turbo.. more laggy and "so what" gains up top. You will need a very long stretch of road to see the K04 nip ahead of the K03S car.

Ive got an s3 and according to my logs it makes peak boost of almost 2bar at around 3.2-3.3k. Takes a bit to get used to with good boost starting at 2k but its economical in that i short shift all the time.

Interesting to know how much k04 pogos make. At the sydney dyno day pogos were capping out between 130-140kwatw with exhaust, fmic and chip.
