This car is a VT Series II HSV GTS (4 door Holden Special Vehicle) , these came out with approx 402 fwhp standard and the kit was manufactured in a place called Cairns which is located in North Queensland, Australia by a company run by Leigh Holman SVS [Special Vehicle Service] in Cairns.ImpalaSS96GTO06 said:sweet...who made the kit and what r those numbers under the sig?
The manifolds are fabricated from what are called "butt weld fittings" here in Australia. They consist of cast steel elbows of various sizes and come in both 90 and 45 deg. and 2 different radius. They can be seen in the enclosed pic. taken after ceramic coating was applied. The dump pipes are 3" dia. down to the 3" cats. then into a twin 2 1/2" exhaust. The plug/wire setup is OK as far as turbo engines go with cyl #4 & 6 the worst. It gets a bit busy down there because of the ABS re-location and the steering. The turbos were put as far forward as possible to make for a better exhaust setup, less sharp bends and as far away from the firewall as possible.DevilYellow said:I wonder what kind of headers they made.... I think they'd have to have log manifolds for the space restriction. I also wonder how large the downpipes are. To me it looks like a spark plug/wire nightmare.
There is room to locate them on the sides of the block perfectly.
Townsville Dragway 15th May !!!!! Cya there ?? :thumbs:lethal said:The most boost used so far is 7.5 psi. We dont intend to increase that with the pressent engine configuration. preliminary dyno tests have been very promising. We expect to see 500 rwhp without any problems.
Unless I am mistaken was the HP originally 400 (or there abouts) rwhp?lethal said:The most boost used so far is 7.5 psi. We dont intend to increase that with the pressent engine configuration. preliminary dyno tests have been very promising. We expect to see 500 rwhp without any problems.
