bonnet modifications

[rs4steve]

as im now keeping my [img]images/graemlins/rs4-button.jpg[/img] has anyone done any bonnet modifications to get the under the bonnet temperatures down?

Mmmmm i dont have a RS4 but ive not heard of any mod`s except for those very very expensive carbon bonnets..... have you got the sportec grills which increase the air flow into your intercoolers..... Jr`s got them on his beast! but it does mean no fog lights! [img]images/graemlins/thumbs.gif[/img] [img]images/graemlins/tung2.gif[/img] [img]images/graemlins/s3addict.gif[/img]

Steve, check out www.fibre-lyte.co.uk . They have made a carbon bonnet with integral vents for the S2. They are not that expensive and could make you something super funky for the RS4. The S2 bonnets saved 20 kg and belive they are less than £500 after tooling!

Get on the blower mate!

Bonnet louvres seem a bit MaxPower, and need to vent into a low pressure area to suck through, and out. I doubt that the area at / near the base of the screen is low pressure though. Exhaust wrap ? Demon Tweeks used to do it. In the early 1990s Abt had a turbo 80 quattro 16v and they had used Escort Cosworth bonnet vents. Vents like in the side of the front bumper, but behind the wheel could suck air out sideways from the engine bay. It all sounds feasible but how much £££.Probably find that you need a combination and even small things all add up to something worthwhile.
Exhaust wrap must be quickest and reasonable value.

Interesting firm, the bonnet vent shape looks reminiscent of the Cossie one, could just be the job though.

Hey Steve, how was Spa?

Good idea and one I've looked into thoroughly. Problem is trying to keep the RS4 non Maxpower [img]images/graemlins/ooo.gif[/img]

spa was wicked had excellent time amazing track 2nd time there now, not as fast as race car overall racecar is 6-7 secs faster did have a lot of over heating problems with my rs4 loss of power etc (the daytime temp was up to 21-22),


the car was unstable in certain parts didnt like fast shifting from left to right since found out damage to front bushes, didnt stop me from blitzing the 355 challenger down eau rouge though [img]images/graemlins/thumbs.gif[/img]

How cool is the Eau Rouge? Must be a pant-wetter [img]images/graemlins/tongue.gif[/img]

Heating problems I had last year were cured by the bigger Sportec intercoolers, but still not enough mate [img]images/graemlins/frown.gif[/img] Watch out for the latest mods which should be in place very soon [img]images/graemlins/tongue.gif[/img]
