    Hey guys,

    i had a previous thread for our shop car..but none of the pics work due to photobucket...so i've decided to delete it and just start afresh.

    For those who are not familiar with our car..here are some details in a nutshell..actual mod list is too long to itemize lads.

    1995 EP82 Starlet
    Built 5E bottom end
    5E head w/mild port-polish & solid buckets (stock cams)
    Dog box transmission/custom twin plate/DSS axels
    Nitrous Express wet kit
    Haltech ECU w/display/logger
    WEPR custom front face turbo kit

    we hit the dyno couple weeks back and the car made 483whp/542 wheel torque with just 2.2bar and 50-shot of nitrous.

    we had to stop because, despite having ARP head studs, the head was lifting. upon closer inspection and dis-assembly, we found one of the threads (block side) on the block for a ARP head stud has got stretched/ruined some how and one stud would not torque down well.

    so once we fix that on the block and get head back on...we will hit the dyno again..

    i know we can easilly go above the 500 wheel mark...how much over is to be seen :)

    Oh BTW..here's the link to the dyno video ... despite a couple guys hanging on the car and having her strapped down as tightly as possible...we could not eliminate wheel spin..

    really massive power there...you all should be proud
    look forward to see what it will do when its fully sorted

    i'm even more so impressed by the tidy fabrication, electrical and work in general

    Mad wee car buddy :) absolutely superb build and quality is epic !
    Looks great too, I'm however not fussed on the massive bonnet buldge, is it functional at speed or ??
    Keep up the good work !

    yes the large reverse scoop is absolutely functional. it helped to drop intake air temps by 7-8 deg celcius on a track day. Here in sri lanka, track temps can go up to 35-38 deg celcius. and this makes high engine bay temps and heat soak a real issue. earlier when the car was moving..IAT's used to hover around 45-46 degrees ...now with the addition of the reverse scoop and vents...its almost down to ambient. (37-38 degrees)

    Here's the current dyno graph...

    ^^Again..these are power figures at the wheel :)




    Right now i am still using a very old intake manifold made by Dale in Sydney..you guys may remember him as the guy who built/tuned Browner's old EP82.

    Once i get this head stud sorted...i plan to upgrade my intake manifold and also step up to a larger turbo...i have a few ideas in mind.. :D

    is this dale "10secrx7"? i think that was his log in name from back in the day?
    i think he used to run a turbo n/a 4efe with td04l and watercooler system??
    all that is off of memory, so i could be wrong...lol

    lol...you sure you need a bigger turbo?...is the current one at its limits for your set up?...you power graph looks very nice as it is, that's why i'm asking

    yes the info above is correct hehe...the ole computer is in good condition :p

    current turbo has a bit more in it..but there is a better combo on my mind i can use.

    We've always pushed the envelope when it comes to these engines because thats how we develope and improve our products mate. you dont discover weakpoints/hurdles till you push. Besides.. horsepower is a drug... errrbody knowzz dat :p

    i can agree with that...lol...by all means push till you get our first 1000whp++ 4e/5e....:D:D:D

    yeah, i know a bigger turbo has the ability to make more power,,,but i also find some projects tend to go bigger turbo and make higher peak whp/torque numbers, but lose driveability and "overall" power under the curve (smaller power band due to reduced size of power curve)...however, in your case, i think you and your team would already have considered such and planned ahead.
    so by all means keep up the good work and i look forward to your progress
    :cool::cool:

    I'd be very surprised if this setup isn't already able to make such power...with a higher octane fuel like avgas...

    1000whp from a 4e/5e is fantasy power...over the years we've seen a lot of 300++whp,,,a few 400++whp....i'm not even sure if we have any 500++whp set ups
    i know spuddy made 570bhp, but not sure what that converts to as whp,,,then there is one more person that made 500++bhp....so that's only two people in that 500+bhp range (we can always talk about this in another tread of via PM)

    anyways, not wanting to detract any further from Sacha's project which is the focus here
    let the mods continue :D

    for a daily driven road or regular track/circuit car..what you are saying is correct..broader the power band..the better.

    but you have to remember my car is built for drag only (never driven on street) and when driven..from the launch, i do not ever go below 5000rpm. my power band is from 5000-8500 rpm. another reason i can go bigger and not hurt my power band is also i use ani-lag and nitrous for spool up :D
