Author Topic: Carbon Chiptuning NW Rolling Road Day - Write Up & Results! New Pics Added! (Read 9180 times)

Ok, so firstly I must say a BIG thanks to Craig & Nick for allowing us to host the day @ Carbon and for all of their work on the day, next up massive thanks to Nige for working tirelessly throughout the day.

Finally thanks to Chuff for getting the ball rolling (even if he did drop out & leave me to do everything

)

The day started with a refresher for me & Nige on how to work the dyno, my car was the guinea pig for this and produced a measly 180bhp

We unplugged the MAF and power immediately jumped to 187bhp suggesting that the MAF was to blame. Nick made a call to GSF & reserved a new one to be collected later in the day....more on that later!

The first car onto the rollers was Bacillus' MK5 Gti:

On the last RR day in April this made 267bhp, estimated power this time was 290bhp. The car returned a rather impressive result:

The benchmark for the day had been set very high!

Next up was Scott v6's Seat Leon Cupra R:

Estimated power was 270bhp due to suspicions of the car having previously been remapped, as it turns out it is putting out stock power:

However the power curve is extremely good and boost is held at nearly 20psi which the guys at Carbon are going to look into at a later date

Following this was Danny's beautiful Mk5 Tdi:

Estimated power was 140-145bhp due to a custom code remap, the actual result was very close:

More to follow!

I think that following this Rhyso's dirty Aldi was placed on the rollers, I say think because Craig & myself went to collect my new MAF!

Rhys refused to predict his power output

His actual result was:

After Rhyso was Ben's newly converted VR6:

Predicted power was 180bhp and the result was extremely healthy:

The next car on the rollers was Brad's simply stunning Mk3:

After fitting nylon spacers between the spring coils to raise the car enough to get it on the rollers the next issue was the car trying it's best to jump off the dyno making it difficult to get an accurate power reading. Nick & Craig managed to add additional straps and eventually got a reading. Bearing in mind this is just a generic map & is still awaiting custom mapping it's a very nice result! (Brad predicted around 235bhp)

**I don't have the dyno plot for the car & need to speak to Brad to see if he wants the result published but it was about the predicted figure!**

Much more still to come!

Looks like a brilliant day

Awesome result Mr Rhyso

Big thumbs up to the Carbon lads once again then

Ok, so I think I might have got the order a little muddled up! Before Brad was Jonny with his Polo G40, after Craig stalling it about 7 times it was finally on the rollers & ready to go:

Predicted power was 135bhp, the actual output was considerably higher!

Again I can't really remember which car was on next, I think it was Matt's Caddy:

Predicted power was 155bhp & 250lb/ft, actual result:

Following this was Adam's A4 (no pics...yet!)

Adam was a bit optimistic & predicted 187.3bhp

His first few runs produced a measly 170bhp(ish), after a few dyno tweaks it was back to what it should have been:

I must apologise for the lack of pictures in this post! I was busy working the dyno so didn't get much chance to take pics, hopefully someone else will have!

I think that this might be in the wrong order (again!) but Gav's red Mk3 8v was on the rollers around this point in the day! After predicting 118bhp (a slight increase on the 114bhp previously seen!) we got it on the rollers.

This turned out to be a very accurate prediction:

Will's Mk3 8v followed:

He predicted 119bhp which was slightly over the completely standard result:

Dom's Mk4 Tdi was next on the rollers. This was an interesting one, it was a 110 non-PD engine with a £99 eBay chip. Predicted power was 137bhp.

When the huge amounts of smoke finally cleared, we could finally see a black floor and the computer screen! The chip seems to have worked extremely well!

Last but by no means least was Mike's Mk3 16v. With a cold air feed, performance filter, sports cat and exhaust this is one of the nicest sounding cars on the day. Stock power of 150bhp was predicted.

The result was good with a very nice graph!

After this everyone f*cked off before my car went back on the rollers which is probably a good thing

The new MAF made no difference to the power so I'm still running 185bhp & 220lb/ft which is down about 20bhp & 25lb/ft of torque on it's last run

After driving home without music on order to listen for any potential boost leaks I'm 80% sure I can hear a hissing when on boost so the car will be back at Carbon in a few of weeks for full diagnostics
