Post your rolling road results here!!


Recommended Posts

Right, I (and several others!) thought it would be a great idea to have a sticky thread for people's Rolling Road plots & figures after having mods done. A single point of reference for anyone who wants to know (roughly) how much extra power & torque they can expect from certain mods.

If you've recently had your car rolling roaded, feel free to brag about the results here!!

Be sure to include the following in your post:

- The maximum power in BHP (and at what RPM)

- The maximum Torque in lb-ft (and at what RPM)

- What engine you have! ( VR6 2.8 , VR6 2.9 , 2.8 24v etc)

- For 2.8 12v VR6 engines, whether yours is OBD1 or OBD2

- What car it's in (Golf mk2, Corrado, Golf mk3 etc)

- The approximate mileage on your engine

- What mods the car had on it (including remaps) at the time of the RR session.

- Whether any problems are suspected to have affacted the figures (e.g. overfuelling, misfire etc)

If you want to be really flash, post copies of the BHP & Torque plots too!

To do this, get them into JPG format (by scanning or photographing them) and host the images on an external hosting site (such as Photbucket http://www.photobucket.com ) and link to them from here, by simply pasting the image URLs into your post (do not use {img} tags as the plots will most likely exceed 500x375 in size).

If you have RR figures before and after a modification (or group of modifcations), so much the better!

Obviously, everyone should bear in mind that different engines can produce different figures with the same modifications. Lots of factors come into play, such as mileage, condition and that some engines just come out of the factory better than others...

I will start with an example from my car in July 2006 form...

Car:

Golf mk3 cabriolet with 2.8 12v VR6 engine (OBD1), approx 90,000 miles.

Mods:

Schrick 268 Cams

Corrado Throttle body

BMC CDA Air filter

Raceland 6-branch stainless exhaust manifold

Milltek cat-back stainless exhaust system.

Custom remap at Stealth Racing

Figures:

Max Power: 203BHP @ 6004RPM

Max Torque: 179.6lb-ft @ 5687RPM

Plots:

Power (before & after): http://i11.photobucket.com/albums/a174/antera309/Nicks%20VR6%20Cabrio%20Project/Engine%20work%20Apr%2006/RR%20Plots/BHP.jpg

Torque (before & after): http://i11.photobucket.com/albums/a174/antera309/Nicks%20VR6%20Cabrio%20Project/Engine%20work%20Apr%2006/RR%20Plots/Torque.jpg

Figures were expected to be slightly higher. Question marks over the cam timing.

It defies explanation. Even when I had the VW Motorsport VSR manifold on there, the car STILL made maxiumum torque above 5K, which is DEFINITELY not right. Vince says valve timing problem (intermediate shaft not timed). This is going to be verified once and for all next week...
