hey guys

thought id put up a few pics of our new engine, graham has been spending ALL his time for the last 3 months building this little ripper, it was decided after the 2.5 mazda let go at eastern creek in may that graham was sik of rebuilding it. the only way it would keep up with the chevs was to rev it to 9000+ and pump 1.8bar of boost into it. SOO we built a 3.5L one instead. the idea being that we wont have to rev it so hard we wont need alot of boost which saves the turbos and also it should be much more drivable

the engine was run in last week and went to the dyno for a tune aswell. it ended up making the same numbers as the mazda 2.5 but comes on much earlier in the rev range which was one of our biggest problems with the old engine.

on the track friday and we had an oil pressure problem wqhich never surfaced before. went home and changed/cleaned all filters etc, checked the oil pump pressure relief valve etc. all looked ok so took it out to see what would happen sat.

in qualifying we found after about 4 laps it runs out of pressure again. it seems the new engine has a higher demand for oil than the old one and the oil pump we had cant keep up. there doesnt seem to be enough suction taking oil back to the tank quick enough so the bottom of the engine is filling up with oil leaving the tank empty so the pump has nothing to re suck up. so hopefully a bigger pump fixes this. we decided to park it before any damage occured.

its a holden rodeo engine.

will put photos up when i work out how. it says i cannot attach files of that type. they are just pics saved in paint to cut down size?

Sorry to hear about the teething problems, but does this mean that you will be traveling now to the other rounds, or using this year as a sort out year with an attack on the series next year. Can't wait to see the pics!!! :D :D :D :D

Hmmm, paint is a bit of a dodgy program. Most versions of XP come with Microsoft Office Picture Manager, best to resize in that and make sure you are saving them as jpg's. Does that help?

sounds like an interesting combo. a mate of mine was at jem when you had it on the dyno and he was blown away by the power of that engine and the noise...

had the car at o.p for a test on sunday (what a fathers day pressie ay)

found out that our tank is definately emptying out so a new 5 stage pump is on the way.
svaenge lines coming from everywhere!

What sort of out put are you getting out of this engine.

[MrBoost]

Hi Wax,

The engine made 780 rear wheel horsepower at 26psi of boost, However we only really ever ran it at 17psi which equated to about 700 rear wheel horsepower.
The torque is through the roof but i cant remember a number. The car and engine are now for sale

Are they seperate or sold as a package.

[MrBoost]
