Plenum Spacer - how long is safe before remap

[buckmoy]

Hello

 

Firstly, apologies to any old timers on here who may have seen this question a thousand times over the last 10 years.

 

I've done a few hours of searching - a lot of the threads descend into (sometimes quite funny) flame wars..but I couldn't see the info I'm after.

 

My car: a 54 plate DE which I've had since 06. Got it at 20k miles, now was 80k miles. As bits have failed I have aftermarketed - so I have a Stillen Y Pipe, a Scorpion back section. Just ordered an Xtreme clutch from Ewen@Clark as the original OEM one is now slipping.

 

Q1: Plenum Spacer. Is this easy to fit by myself? It looks (on the face of it) quite simple in so far as - remove plenum and brace, add spacer, refit plenum, adjust brace fittings, refit brace.

 

Q2: How long is it safe to run before I should take it to Horsham/Abbey/somewhere not UpRev licensed for a remap? I've seen people talking about the danger of a leaner AFR mix brought on by the ECU being a f*cker and adjusting for the increased air flow.

 

Thanks - sorry again if this is answered elsewhere, must be like groundhog day on here for some of you..

If you can wield a spanner you'll be fine with it.

 

Fine to drive with it on. The ecu should compensate for the increased airflow (is the general consensus)

Just don't over torque the bolts as you might crack the plenum.

 

I had a similar set up with a spacer on for years and I never had a remap

Or drop a bolt down the intake (husky)

There is a post on here by ZMANALEX which shows the torque of the bolts to put the plenum back on at as well as the order in which to put them back in. Im average at best with spanners and I managed to put it in no problems on my own.

Great stuff, thanks all.

Easy job but as Col says you need to follow the procedure for the order of removing and refitting the bolts and make sure the torque settings are correct. Also be careful not to damage the gasket.

Cool. Thanks for the pic. I couldn't find the ZMANALEX post but found this useful PDF from Motordyne with detailed instructions: http://www.motordyneengineering.com/manual.pdf

Mate, that is spot on and what I have always used. It really isn't a big job, just make sure you note which bolts go where as there are different lengths. Good luck.
