View Full Version : REVO 4 Bar FPR Dyno
These are the VAMAG and Dynapak dynographs of the REVO 4 Bar programs. The Dynapak graphs are a little choppy because the dyno bolts directly to the driveshafts, which is good for eliminating tyre losses, but it also removes the considerable flywheel effect of the wheels and tyres, which help smooth out the power delivery of the engine.
I have also included the Boost graph of the Dynapak test for reference. The Vamag Dyno will be shortly updated to show, Boost, A/F ratio, Inlet Temp, etc.

I see there is 20psi boost being produced on this engine...
Std K04?
Bill
High boost setting for REVO programs is 1.4Bar. Car is absolutely standard. If you doubt the results, take a 4Bar car to Jabbasport to test on their VAMAG dyno.
Its not that anyone doubts the power.... its just that 20psi from a K04 seems very high. I didn't think it was safe to take them over about 17psi at the absolute max.
I could be wrong.

Did I question the results?
No.
You need to relax I think... not everyone is doubting when they post.. ;)
1.4bar will run some mighty induction temps. Good for peak flash readings but how would it be on sustained high throttle loads?
Just asking... :)

Hey Bill, don't take Jon personnally he's having 'email' problems today!;)
Bill & Ben (where have I heard that before)
I went back to stealth again week before last and had boost logged. Mines running 1.4 bar from when it comes on boost, to about 4.8K.
We logged induction temps, and the highest we recorded on 3 runs in about 10 mins was 45C. The fan was turned off between runs. On one run the temp at the start of the run was >30C Each run's about 12 seconds.
On the road theres more airflow over the IC, and 12 seconds of full bore in 4th is enough to go from 40-100 in 4th or 50-100 in 5th.
Other than on the track, how often do you get to do longer full throttle runs?
I've got to do some temperature logging on the road in the next couple of weeks and will do more as the weather gets hotter, but the car doesn't seem to noticably heat soak, even after prolonged abuse.

All I can say is you have a mighty impresive IC there on your Golf... I wish Ibiza ones worked as well. :)
I have seen 50+'C induction temps after only 20seconds full throttle on the road... On track it gets over 70'C which is mad.. and wilting..

I've got the uprated forge side mount which is quite a bit bigger than yours, and handling only about 2/3rds of the air.
Just out of interest, on the road, when can you hold full throttle for 20 seconds? Even on the track this must be hard without crashing? I can see it might be a different story on the track!
Full throttle from a standstill in mine gets to about 120 in 20 secs, so youd be hitting 150mph?
The induction temps seem to drop prety quickly when I ease off.
Hallo,Tamiya.I have already been revoed.Can you tell if the 4BAR REVO software is available for the IBIZA CUPRA?

20 seconds full throttle does get quite a speed...
Track use is where I need to have ample intercooling... as tghe sustained load and heat input is shed loads higher than on public roads, where you would just get locked up!
Golf unit is much better than Ibiza, let alone Forge Golf upgraded unit. My comment re high boost is for those running stock IC, and warm weather. We have yet to see the summer here. (wishfull thinking)
Bill
Forgetting the induction temps, is it safe to run a K04 at 20psi?
Cheers
Ben
well on the car in the dyno it's a K03, and I've been running mine at 1.4bar for 3.5k now whith no problems. Plenty of guys in the US running K03's at 20psi, and k04's a little higher.
People running 25psi plus on k04's seem to be blowing them up though.
I guess only time will tell.
here's a third gear boost log i did yesterday

Do you have a plot of that same boost with induction temps superimposed?
Mine go sky high at the moment... and limits what I can run...
(eg from 30'C to 76'C in 20seconds ! - Roll on the charge cooler ASAP!)

I don't think 3.5k is a significant test... 30-40k maybe.

Bill I've logged inlet temps for a similar run and with them starting at 30C they rose to low 50's for a third gear blast from 1.5k to 7k.
I did a 30-110 in 4th and logged temps, and they went from 30-51. They drop back to mid 30's within about 10 seconds as you ease off.
You can look at the plots on sunday if you like.
Ben as of today it's nearly 5k. Generaly if things don't let go fairly quickly then they'll last. And hell a K03 sports only about £250 with a few miles on it.
Anyway I did my best to blow it today in on a northern french autorourte. I was running at 140-150 (6k in top at 23.9mph/1000rpm) (12mpg) for about 15 minutes with a 911.
Had vagcom running and induction temps were solid at about 58 degrees. I just wish I had it logging them. It was only 8C out though
Pulled up sharpish to fill with fuel, popped the bonnet and the turbo wasn't even glowing. (it was quite warm though)

what is the block number to measure inlet temps???
Also will a K03 Sport make much difference if I upgraded to it from k03??

I think you should be the "official forum nutter" mate :p
140-150 for 15mins... :laff:
