Hi All, I recently upgraded my RB20 with coil packs, fuel pump, full exhaust system and then just put on a AVC-R boost controller. I sent the duty at 30% as my friend did to his subaru and it runs at like 16 pound on the stock turbo? I think this is too much am I right? Sometimes the car feels fine but then other times like it is a little sick and all elements are not running in correspondance? Any suggestions on this at all or thoughts?

yeh, its about 2-4 psi too high, the sluggishness will be because its running mroe boost than it can do efficiently. Won't last long either, 12 psi is about max you should pump through these

ive been told 14 is safe.

how much boost hasnt really got anything to with it. i've fried turbos on standard boost. but as a general rule/experience under 12-14psi is ok for a while. its not like you run 14 and its sweet then 15 and it carks it.

there is no point running more than this anyway with a standard turbo and especially with no fmic. anymore than 1bar is really out of the stock turbo efficiency range and yer as stated, just pushes hot air with not much gain.

problem shouldn't be the ebc. so wind back the boost and/or strap on a rb25 turbo and get a front mount!

and yer, cant beat a bleed valve for simplicity and value! most fun you'll have with the lads in your new beast at night on a quiet road...

      If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.

      In the US almost everything is E10. It can't exceed 10% by much or fuel systems have trouble adapting. At the same time because MTBE, MMT, and TEL are all banned they need as much ethanol in it as possible to boost octane.

      I was mostly jesting. In my experience (and probably only my experience) the R34 GTT physical airbox space is actually too small to flow the amount of power it wanted. By sealing the box, I made it so it could only be fed by the ducts themselves. So you can seal it up and get nice cold air which IS good, but at a certain crossover point: More Hot Air > Less Cold Air I don't think you're at this point. In my case merely ducting the hot air intake with a very focused set of ducts counteracts the fact it's in a V8 engine bay. More cold air obviously best. The solution looks great.

      Nah, the OEM CAI pipe is still installed behind the bumper, it is about 5" x 3" oval at the engine side, tapering down to a 3" pipe behind the bumper where it gets all the ambient air it needs Engine side of radiator support OEM intake pipe "oval hole" that is right in front of the filter My OEM NC1 CAI pipe: From NC2 onwards, below pic, they come slightly smaller at 2.75" diameter with corrugations and a resonance chamber to reduce intake noise, lucky for me my NC1 has the bigger noisy one, LOL   Basically, the "sealed" airbox will just get ambient air from a 3" pre filter intake tube that is the same size, 3" as the rest of the intake pipe post filter, and if a 3" intake isn't big enough to flow enough air for 150 killerwasps then there are other issues The whole intake is basically the same length as OEM, but it is now about 30% bigger from the airbox back through to the new intake plenum than OEM, and the intake plenum is port matched to the head And the intake is now about 30% bigger than my 2.5" exhaust, so the suck, squeeze, bang and blow black magic should be fine, well, to my uneducated understanding of fluid dynamics anyway Talking the the guys at MX5 Mania, it may even make a few more killerwasps as the intake isn't sucking hot air, especially off idle or when in slow traffic when it would be sucking hot air  As for the difference in IAT, I haven't logged IAT yet, as I don't currently have a OBD2 reader, but I will have a play with my thermal lazer thingie next time I take the car out to sèe how hot stuff gets under the bonnet near the intake filter prior to installing the air box, my "assumption is it has to be much better after the air box is in and sealed up compared to what it is now The aftermarket "performance" CAI elephant in the room: Aftermarket CAI intakes typically have the air filter tucked up behind the bumper, with a 2.5" intake tube (the OEM intake pipe is actually about 30% bigger than the fancy pants "aftermarket" version.....WTF), and you need to remove the bumper to service the filter, which is a PITA Like dis:
