cheers for putting my name down looking forward to this event sounds like some awsome cars are going to be there cheers shady

 

 

Sounds impressive...look forward to seeing the results!

 

Cheers mate,

Interesting to read.

Im spec'ing a similar spec build at the moment. What turbo are you using at the moment?

7750, is that your current rev limit or are you pushing past that?

 

Love the stealthy Sleeper look, good to meet you Thurs, cracking spec.

Plus responsible for one of if not the best thread on here this year

Kept my smiling for weeks

 

Hi Frayz,

Yes after all that text forgot to specify the Turbo - DOH!- GT35/42R, the compressor housing is modified to prevent/minimise surge, but this was carried out by the previous owner- so not sure what this entailed. It also has a Tial external wastegate near the bottom of the the down pipe. Boost is controlled by an AVC-R and the 3 port solinoid valve is fitted on the inner wing, down by the waste gate, as this improves response.

I geared the car to pull 130 at 7750 in 4th, I did this by fitting a wide ratio forester STI box (rockinghorse S##T) and 225/45-17s. I did this, because the car will pull c130 terminal speeds on the strip. This means one less gear change from when it was running a 5 speed, so in theory, should improve standing quarter times,(If only I knew how to drive ). The 6 speed weighs c. 18-20 kg more than a 5 speed, but I compensated this by fitting carbon boot and bonnet (saving 15KG- and lightweight wheels-saving 8kg)

So to answer you question about rev limits, 7750 seems to be a safe limit for 2.5s of this spec, after this its running out of puff (relatively speaking), but I often run 8000 in 4th at the line to prevent a gear change when drag racing.

The last time is was dyno'ed it run 525/550 running a GT30, but since then a GT35, two fuel pumps, and bigger injectors have been added. So I will be interested to see what it makes on 28th. (Assuming nothing breaks before then, as Im at Santapod on 22nd Sept.).

Regards

Sleeper.

 

Thanks Yellowvanman,

No one ever came back to me to say whether Turbonators are legal or not.

I guess it will be one mankinds unanswered question.

Sorry if im taking the thread off topic.

 

Cheers mate, sounds great. A splash of meth on the 35 should see you well up in the 500s depending on your boost level and profile.

Looking forward to seeing the car and its results. Thanks for sharing

 

due to the arrival of my new car i can now comfirm
it may not be to good on bhp but
being a diesel it will be great on torque

budgie

Could everyone have a check as I may have cocked up this list

 

need to organise a meeting point for the way up there. would like to get there for the first car on the rollers. need to take some pics

just to warn everyone and to ask them not to laugh at the power figure my car will produce after seeing 3 mocom monsters on the rollers before me

 

Yes, thanks for organising.

Sleeper

 

Wonder if they can dyno my bike

 

Depends.....

Is it 12 or 18 speed?

 

Can we not keep the running order as per the original list. I might not have confirmed/paid but I got my name down early for a reason.

 

18 of course, with full suspension and a gel seat

 

Yep... leave it with me... As I said, it was done rather rapidly.

The running list will reflect confirmation/paying
