My new engine - tuning *update* 25psi ='s :D

[Chris32]

yeah, RE55S will be available in hard soon. I was sold the soft 'wet' compound tyres! so hence the short lifetime of them

Nice dyno result Matt

[Nightcrawler]

top work Matt .... I hope I can get a few runs in alongside you qualifying at the Nats

[whatsisname]

Thanks mate Yeah a bit of side by side fun would be good First things first though I want to concentrate on getting some decent numbers.

Shaun will be doing a bit more tune work tomorrow (the CR allows more timing to be added) so a few more rwkw would be nice. If we can sort the boost drop issue (small but worth rectifing) before the nats that'd be nice too.

I guess I could go crazy with boost but to be honest I'd rather keep it closer to what I'll run on the street. I'm not out to set any records (don't have the power for that) Should be good fun

[hippy]

how about changin that suspension setup u got .. i think u need some soft ohlins or something matt

[Busky2k]

Nice power there man. I gotta see this beast in action one day

[BOOSTD]

Go the Hybrid's ! Was that number made on BP98 matty? My last tune as was with a fair dose of octane booster and some aggressive tuning. Nice to make that much more power with a piece of mind to go along with it.

[whatsisname]

Hip,

Yeah a decent shock upgrade is in the pipeline (shocks are the only sus mod left to do).

Busky2k,

I'll be at the Nat's, but who cares about my car I want to see Munro & Keir running 8's

Matt,

Yeah mate nothing but good ol' as it comes out of the pump BP98. Hopefully later today we'll get to see how much more it can make 'safely' with more timing & a bit of octane boost.

[BOOSTD]

so sweet. I am running 8.7 CR will be interesting to see how it goes on BP 98.

[whatsisname]

Should go very well.

[TIMMMAYYY]

speaking of munro, will his 33 race car be ready?

[whatsisname]

We did another tune today. Added an extra 1' timing. Got a nice even 280rwkw on 1.3bar. The wastegate is creeping up top so it drops to ~1.1bar. After we sort out the actuator it should hold boost & make a few more kw up top. Dyno sheet to follow soon.

Only downside so far is that even when hot the RE540S's no longer maintain any traction This on 1.1bar road tune. Haven't tried 1.3bar yet.

The LT12 handset is able to hold 4 maps, so they are set as follows:

1. 'Valet' - 3000rpm limit / 3500rpm cut

2. 1.1bar road tune

3. 1.3bar road tune

4. may become ELF LMS drag tune

[hippy]

i'm interested to know ur mileage stats with the power matt ... 250km pertank?

[whatsisname]

All depends on the right foot mate. I got 260k's from 1/2 a tank during the mild post 1000k run-in tune. I'd be pretty happy with ~400k from a tank with mixed driving (cruise/WOT etc...) Heavy driving & I'd guess 200-250k? Can't have everything

Once I've done a few k's I'll post a report on economy.

[whatsisname]

1.3bar dropping to 1.1bar. Time for a better actuator.

[Bl4cK32]

Just a quick question, have u worked out the "average useable power" ala Sydneykid's reckoning?

[whatsisname]

Very good question mate. Yeah I have had a stab at the average power (sydneykid style)

I know the power curve stops before 180km/h but I'm guessing that the power would drop at a similar rate hence I can estimate power at 180km/h mark (it should improve in this area once we get the boost to hold).

So based on the above my average power reads as follows:

3,600 - 213wkw

4,600 - 272rwkw

5,600 - 280rwkw

6,600 - 245rwkw (boost drop takes effect here - "should" improve with new actuator)

Average power ='s 252rwkw

EDIT: Given that my cams are still stock (so far ) I'm very happy the bulk of the power is btw 3,500 to 6,500. We all know rev's are far less kind on a motor than boost (providing the tuning is good).

A nice set of Tomei VCT friendly Poncams should just about do it.

[Bl4cK32]

Well done. A nice set of cams, and actuator should see the number go up

[whatsisname]

Cheers mate Actuator hopefully early next wk. Cams later down the track.

[Busky2k]

Wow I just love the midrange grunt of your engine. It has more power at the wheels at like 3200rpm than mine does at peak power (6000rpm)!

It should haullll ass...

[knore]

So impressive, i think youve done what alot of us want to do

great thread

-How much is the 4map microtech your running?
