South West Rolling Road Day *25th August*

[Craig-rev3]

Hi everyone,

A few people have mentioned in the Marlborough thread that they'd be interested in a rolling road day.

So if you are interested add your name to the list below.

I will contact Mtech, who we used last time and see what dates they have available along with the cost involved

List updated:

1. Craig-rev3
2. madbasshunter (engine dependant)
3. chaos19810 (engine dependant)
4. Tinker2
5.Megamonkeyman
6. Yose_gt

Prices are as follows:

5+ cars - £35
10+ cars - £30 (plus a complimentary hot dog)

As per usual you will get 3 power runs & a dyno printout

This will be held on the 25th August. I will you guys know if we need any deposits ect closer to the time

[madbasshunter]

I will be if I have fitted my engine

[chaos19810]

Yes, date depending

[Craig-rev3]

It would be good to see what yours is doing Shin, especially with all the work you've put into your engine

3. chaos19810 (engine dependant)
4. shinny (date dependant)

i've just sent M-Tech an email, I will post up prices & the dates they have available

[shinny]

Well yes - who knows what's it going to push in the end! I've never had that engine dyno'd, although it's never felt quite as fast as the old engine.

That said, with a massively free-flowing breathing setup, the ST205 ECU and a custom wastegate coupled with a Gizzmo so I can control the boost without fearing creep, I'd hope I could push a smidge over 300bhp. That said, a healthy 290+ run on Dyno Dynamics rollers would satisfy me, as not all tuned 3s-gte engines actually get to 300 for some reason. Besides, peak power has never been the end goal... fast spool and a strong midrange is more important to be really

[Craig-rev3]

I know you don't target BHP & focus on as little lag as possible, but I'd have thought a target of 300bhp would be very realistic for yours Can't imagine it being too different to Ant's old car in terms of power.

[shinny]

I'd hope so... I think alot will end up resting on how well the chargecooler is working TBH. But we've seen the ST205 ECU gives a few bhp at the top end, so I'm hopeful for a reasonable pub bragging figure too

[Craig-rev3]

Didn't think you were into pub bragging?

After my last 2 attempts I'd be over the moon with stock power!

[shinny]

Nah... but it's always nice to have a good figure when people ask

Regarding the ECU, Toxo did a back-to-back trial a couple of years ago on stock boost (0.96bar), and gained 9bhp at the wheels using the GT4 ECU:

MR2 Rev3 Turbo ECU, at flywheel:
275bhp at 5800rpm
280ft/lb at 4800rpm
231 at the wheels

ST205 ECU, at flywheel:
283.7bhp at 5800rpm
277ft/lb at 4800rpm
240 at the wheels

So, if everything worked perfectly, the most I'd be hoping for is 310bhp. I'm too pragmatic to think that's what would actually happen tho :blush

[coley29]

I'd be up for this depending on dates, might even have the cams in in time for a good test

[Craig-rev3]

Ahh you've whipped out your ninja figures

That does explain why the GT4 has about 10hbp over the MR2, I'm assuming with the chargecooler in place, Toyota ran a more aggressive base map & in Toxos case with other breathing mods that adds nearly 10bhp to the wheels.

We'll have to see what happens on the day, looking forward to it

I'm interested!

Came along for one a couple of years back, engine has been tuned a bit since then and I wouldn't mind finding out how the figures have changed. I'll keep checking the thread.
