Hi all,
This is my drag car. I have done all of the work myself, Jayme has been my tuner/technical adviser along the way and has been bugging me to write a thread for a while. There has been a bunch of history that will take all night to write out, so ill mainly concentrate on the current specs. the short story is that initially, I built it with a twin TD04 turbo buick, and after many hours of playing and new parts and retunes, gearbox upgrades, brake upgrades, etcetc we blew a motor and decided to repurpose the Ecotec I was building for my road car, and use it for the drag car instead.
The car is a 1979 mk2 2 Door Ford Escort, with an R31 skyline 28 spline Diff Mounted on a 4 link rear end, commodore rear brakes, Volvo 4 pot front brakes, 2x VH44 remote mount boosters (one for front/one for rear), front coilovers, headlights removed to make room for intakes.
Engine is a Ecotec v6 with Come 4.2L stroker Crank, Diamond Pistons with file fit rings, H beam Rods, Girdle, ARP bolts throughout, 0.060" cometic gaskets, 1.6 ratio yella terra rockers, custom Camtech cam, 70mm throttle body and cut/welded/ported and enlarged neck to suit. After cracking a pair of heads, went back to stock heads for now, with stainless valves, manly springs+retainers etc. providing Boost are 2x GTX3582's with 0.8AR rears each mounted on a custom 3 into one exhaust manifold, feeding a 2 in, 1 out front mount cooler and 3" mandrel bend dump pipes exiting behind the front wheels.
controlling this is a VR auto computer running 11P, 1000cc injectors and a VL400 coil converter box driving 6x ls2 coils. The sad 4L60e is being replaced this week with a built TH350 with manual valve body and 4000rpm stall converter.
This week I finally made it to the Dyno and after a few hiccups with dwell settings, and a pair of shit tyres that kept frying on power runs (dynos hate slicks so I had to run an old shit pair) , we got it to 425RWHP at 17psi boost on 98 octane pump fuel before it blew a tyre. this dyno reads light, so these are real hp
we have taken cars to 'gold coast special' dynos and they read 50hp more!! [youtube]https://www.youtube.com/watch?v=aanDEsNFduA[/youtube] ill let the pics do the rest of the talking. Apologies for the shitty iphone pics. ill take some decent ones once the front end is back together.
