Well Chuffed now..!!

Ok as some of may know I had a problem with fueling and after doing some reading last week found of it was the vacuum hose on the FPR had come off the MAP sensor outlet, so that went back on. So it was back to Abbey Motorsport this morning for another dynopak session. I have a Greddy Profec Spec B Boost Controller fitted, while dyno running we set the controller up but it seemed to be having a prob controling the second turbo. Was told this could be a leak in the vacuum canister as the boost dropped a bit..? It has been recommended that I run the turbos as a matched pair, i.e full twin not sequential. I know this can be done electronically, but is there a way to do this mechanically..? and how do I know if if the wheels are the size same..? Will try and scan the graph printouts and get them up on here soon.

Why am chuffed though, car made 374.4 BHP at the hubs @ 1.2 bar boost..!

Cheers Jake, most helpfull..! and so the turbine wheels are the same size. Cool, off to get some parts then..!!

Nice one James

I have mine running in parallel, with the emanage mapped accordingly, much prefer the parallel setup personally, as the power delivery is much more linear. You sacrifice a little low down, but gain power/torque mid range, which after all is where you do most of your driving.

However I wouldn't recommend it unless you have some way of remapping the fueling and ignition to cope with it.

Yeah an emanage is next on the list, after i find some more cash lol...!
