DPJ's GTRS Eliminator Install and Development

115?

If it were me, I'd be out with some spare jubilees, turning the fecker up.

115?

If it were me, I'd be out with some spare jubilees, turning the fecker up.

I was going to but some cheeky bugger came to use my test track. If I'd been him I'd have taken the thing off the roof that held the pretty blue, red and white lights first.

Crank the boost up dave. Lots! Logs look pretty good to me still.

If you had to guess the power now compared to the k03s what you reckon its pulling?

It looked the same way to me...

 

[wild willy]

Those logs look pretty good. Fueling is running nice and rich keeping egt's down. Nice boost hold post 6000 rpm. I would expect a little higher mass air readings as i achieve a little higher 208g/s measured 48hrs ago at slightly less boost.
I recon your running aprox 280 bhp.
I'm well jelous

 

[m0rk]

the MAF is scaled though, so you can't really guess at bhp (I think)

You're right Mark.
I'm not even sure it's a case of (LCR Maf tube radius)^2 / (LC Maf tube radius)^2 x g/s

Just off out to do some logs. I may be some time.

correction factor near 7.... bit high on the time id say!

cat temp over 800 sounds high to me also

im running 800C at start of DP

Take the timing back a bit then?

There can't be a massive heat loss down a straight DP from turbo > Cat.

 

[wild willy]

Looks good to me mate.
Fueling good, Air mass good, A CF approaching 7 is acceptable i wouldn't worry about it. Remember its still learning and adapting. Surprisingly high intake temps at high revs considering fmic. Duty cycle looks like its not even trying.
that power must be giving you a few white knuckle moments.

Don't forget a proportion of the intercooler is covered up at the moment. I need to do a bit of hacking!

The power is really fun as long as you remember there's sod all happening sub 4k, so you need to keep it on the boil. Wheelspin and torque steer are a bit of an issue in the lower gears. Overtake on full boost, and the car you've passed is suddenly a tiny dot in the rear view mirror.

Thanks for your input, Carl.

more hacking your car is now stage 3 weight reduction isnt it?? lol

There's a bit to go, last time I weighed it it was 1380kg with about 20 litres of fuel.

HB9 T5/6 then Unless heat is an issue, highest MAF reading on HB7 T7 log

Certainly delivers boosts at the top end. Monster.

Not use to seeing more timing pull low down then less higher up...

Using your formula for scaling what BHP does that give (I can't remember LC MAF size)

 

[ibizacupra]

Take the timing back a bit then?

There can't be a massive heat loss down a straight DP from turbo > Cat.

i am told its 100 degrees from pre turbine to post turbine which is a lot less distance.

I was hoping someone would come along and explain that.

I'll go and measure the ID of my old tube now. Do you know what the ID of an LCR MAF is?

Has the turbine a lot more mass to take that heat drop compared to the DP?

Can't remember - I posted it some time ago, but can't find it now...
