    Here’s a couple from a BHCC car

    You have to both move a lot of air and compress it. 200HP needs about 140CFM but all of the 140CFM fans you can buy won't help :D Purpose-build eSuperchargers don't seem available at the levels...

    All things being equal, .75 -> .79 would be a nice improvement and probably wouldn't add significant oversteer.

    That thread is a photo essay of what a decent RSB would tame.

    You can buy a kit for a VW bus so I'm surprised there aren't any options for our modest sports car.

    Spax + high rate front springs. Further increasing rear spring rate or stiffening the dampers to compensate would likely compromise overall ride quality. Since Michigan roads are awful I'm trying...

    My goal is to cut down on the massive body roll. Even a little more roll control in the rear should go a long way to improve cornering feel. I get a little sad in our local roundabouts.

    Last time I harassed Toby, word is that the RSB project is a no-go.

    The Addco mountings could probably be reworked, but the kit is no longer available and I haven't seen one come up for sale in...

    Do this, then the center tabs will line up, and you can push it back to right and lock everything in to place

    After finding some free time for a few thoughts and image searching LT1 throttle bodies, I think you're seeing the effects of going to both a larger TB and a linear pulley.

    The stock DMC throttle...

    I'll admit I haven't spent a lot of time here as even the stock curve worked well enough. I've enriched things just a little bit versus stock but the last session I recorded shows I could use a...

    I'm on MS3 and we're plumbed differently enough that my values probably won't be useful. I've intentionally messed with the minfuel to gain more resolution in the VE table so I'm 100+ above 85 kPa.

    I can see how a larger throttle body can affect the granularity of the throttle input - turning the pedal into more of an on/off switch than a linear input. Unless the TB is comically oversized I...

    The decel valves probably reduce the effective TB size a little.

    What issues have people had tuning with the stock intake?

    eBay puffery aside, that's kind of an interesting swap. I think that's a 3S-GTE Gen 2? Would be from an 1989 - 1993 MR2.

    Intake and air/water intercooler look unfinished, just kind of hanging...

    Per turbo


    I think we're looking at the same documents. It's a big chunk for sure. I wish they detailed what kinds of conditions those failures were occurring at. Opening the ring gap coupled...

    Ah, interesting. Thank you for providing actual data!

    This says to me that the spark map is not good and is probably hurting performance.

    300 HP cocktail napkin math:
    Legend baseline n/a engine: 127HP @ 5600 RPM
    VE = 64.42%, 96g/s airflow

    To...

    Understandable. I suspect all of the issues related to legend motors knocking under boost are related to improper spark timing. That's why I'm curious about if the ignition distributor was...

    From the materials I have reviewed I don't think it worked very well. But there is a lot of pen-on-paper theory and I don't really know what was in prototype when they folded.

    Out of curiosity,...

    I did it for the learning experience, and because it was fun, and to have a one-of-a-kind setup. Plus I have no place to store even half a drivetrain, so I could do most of the conversion in situ.

    Having turbos installed in draw-through confounds the root of this issue. Horsing around with my own draw-through setup I was "gifted" almost every failure mode in this regard due to a variety of...

    Normally I’d say to pick up some cheapo 1.25” aluminum tube and sell the otterstat piece, but if it’s leaking then no sense in saving it.

    I have a pipe bead roller - a luxury that's useful for those few times you need it.

    If you send me a pipe and return shipping I'll bead yer pipe. If ya know what I mean.
