holes up in the parcel tray to mount the back straps to
maybe a steel plate underneath for extra strength, but ive seen tracked cars using same spot for harnesses, I wouldn't make a habit out of it but would do till you make up a harness bar which bolts through two plates welded to a bar under rear seat belt mounts on C pillar.

I have mine mounted to the parcel shelf Steve, I just had to fit a plate underneath to pass Cams scrutineering.
Will post a pic tomorrow of the plate and measure it up for you.

[steve]

Thanks mate, the dimensions would be great so I can arrange one this week while the car is away.

[marinetowing]

It's a steel plate Steve, 7mm thick, 6cm wide and 9cm long.
This passed cams requirements with no dramas.

[steve]

Thanks for that mate, it'll probably make a bit more sense when I see the parcel tray.

In good news, the car just came off the dyno with 21psi in it .. made just over 300kw atw with the smaller exhaust housing.

I'm stoked

:shock: Nice work mate!
I will take a picture of the mounted plate for you Steve to give you a better idea.

maaaad


I wonder if ill come close to 300 with the new setup :?

[steve]

What turbo are you going to use? I had a quick look at your thread, but couldn't see anything.

[GSRSOL]

Dude, that's awesome!!

I saw your car at the IS dyno day last week, was hoping to see it on the dyno to scare the crap out of the newer EVO owers!! :shock:

[steve]

Were you the guy with the VR4 there? I asked about 5 people who the car belonged to so I could have a chat with the owner, but noone I asked knew

I picked it up tonight, final figure is 426 (point two!) hp atw on 24-25 psi. It's an animal again, love it 8)

Nice. Very nice. What was the final difference in boost response?

[steve]

It's not as good as it could be, but it's still far better than before.

On the dyno, Mick could get full boost in at 3600rpm, but the motor didn't like it - it'd miss and break up, so it had to be staged to come on a bit later. It's making 10psi at ~3800rpm, 20 psi at 4500rpm and 25 psi at 5000rpm.

The difference in power is pretty noticable though .. see dodgy table below lol

RPM     0.63     0.82
4500    190hp    140hp
5000    300hp    250hp
5500    350hp    350hp

So there's a good 500rpm difference in where it's making power. When I finally get around to putting an inlet manifold on it (I've been talking about it for months now), we'll index the plugs and maybe make some changes to the ignition setup to see if we can bring it on earlier - another 500rpm will make it very nice to drive.

On paper, the powercurve doesn't sound too good, but to drive, it's brilliant. Nail it from 3500rpm and it spols up and starts making power almost instantaneously, and by 4500rpm, it's time to hold the fuck on. It peaks at about 7100 rpm, and then starts to dive off, but it's still making ~400hp by the time it hits the rev limit at 8000rpm.

Yeah, that's my old girl..

We'll have a chat at the next meet for sure mate.. I was actually looking forward to hearing your beast on full boost! Hopefully at the next meet.!! 8)

[runuts]

Awesome result with the .63 Steve.. must be fun to drive.

[OFFON-4]

Looking good Steve 8)

[bazeng]

Very nice!

So the .63 is overall much better suited to your motor..

Have you tried upping the boost?
I'm just curious to know what the differences would be with the higher boost pressures and different sized housings... (in real world testing on our motors)

[steve]

We think it actually made more power with the 0.63 than the 0.82 (though we are running more boost now).

Dyno sheets

0.63, 24-25 psi (current)


0.82, ~21-22 psi (old)


It did make 436hp atw in the past, but that was in 3rd gear. Both of the sheets above are in fourth, so should be a better comparison. It trapped 127-128 before, so we'll see what it runs on the weekend (if it holds together )

Intake temps were higher this time around, but a quick manual calculation showed that the correction that was applied would be next to negligible.

[CLuTZ]

Wow. That curve is FANTASTIC. All the best for this weekend steve!
