Great to see another Cosmo in action! I looked high and low for a good one here before I gave up and started my FC conversion. Great numbers too - she must go like a trooper =) May I ask torque figure?
All the best!

BTW - I love the greater than 45% climb in power at around 90 to 120k's. It must throw back in the seat like a rocket with that acceleration!

TDIT

Argh! I meant to say greater than 45 degree angle climb!
What can I say - was a jim beam moment...!

[QUOTE=Taylorjones;10358213]have you ran it in the 1/4 mile?[/QUOTE

It did do a 400M run once at a local Sydney strip. Its a 13.0 car I'm sad to say.

1600kg. Auto. ***** driver all make it nothing special

Sounds good Kev.

However, im on full boost at just 1800rpm pumping near 400NM of torque by 2000rpm. Makes for very responsive driving in traffic

REgards

DMRH

The FD runs 2x HT-12
The JC runs 1x HT-15 + 1x HT-10

Since performance is as strong as the "weakest link' That little HT-10 at the rear is very limiting....

DMRH

No, its a "weekender" at best. 3-car family

Family car + Company car = little time for Cosmo even on a weekender basis.

Torque really pushes you back in the seat at that point. Shame the turbo flow wont maintain that power curve.....

TDIT

Still impressive for a Cosmo =) Even though I know you have a little work yet to do It's still a great achievement =)
Love the Cosmo's, they just have a way about them that's cooly regal - was waiting for the day a mate of mine might sell his - then it got nicked... =(

it's odd that the primary turbo charger, the front, is the ht 15, and the ht10 is spooled secondly, rather then the ht 10 first.

likely why the FD turbos can see 15psi of boost, yet it's 1800 on the cosmo in this thread.
which makes this a lie: BNR Upgraded 20B turbos.
The primary turbo charger is actually the gt 28, and the secondary turbo is the V trim T04B, a smaller "helper" turbo, rather then the small one being spooled first for the highest possible boost responce.

TDIT

I don't see it as a lie at all imho. If I recall, this car is running stock turbo's in parallel right? So if both are running, then the smaller one would become restrictive at the higher end. A 13sec Cosmo is nothing to be sneezed at. They are a HEAVY beast, and with stock spinners the boost would be limited by what was described as the weakest link. This car has both turbos spinning at mid range, which is why the mid range rate of accelleration is so high - and also why the boost drops off at the top of the range. For a weekend driver, I'm in favour of non-sequential twins with a bit of porting. It makes the car "more" drivable because it add to the potential mid range. All that would be essential is a clever boost controller - which he has.

Sir, you and I are from different planets.
if it's not sequential, and it's not a v6/v8, then it should just be single.

His is Sequential.

if you *completely* understood how the system works, you would realize that the smaller turbo cannot be restrictive to the system, if it's sequential or not.

TDIT

LOL =) Nar, we're on the same one. I shuld clarify my comment a tad though. I was referring to the twin setup the RX's and Cosmo's use. We know they can be (in stock condition) prone to failure where as the first (smaller) spinner is always running - which in the stock system lead to heat related failure. The mods that can be done (rather long story short - but I'm guessing you know about them(?)) involve changing them from sequential to non, with major mods and rework to the twin setup that allows both to run all the time. In that sense, I am in favour of non-sequential.

On my 20B I went single, but getting early boost/ positive displacement was extrememly important to me - even though the 20B has a lot more torque than the 13B. So I spent a bomb getting a high perfmance/ efficient turbo to suite my needs. If I couldn't have, I would have reworked the twin setup into a non-sequential. Luckilly for me, that never became necessary.

PS: Yep, I "recalled" wrong - bad me, bad. I'll go find a tall brunnet to spank me.

PPS: I wonder how he's going with it. This is a nicely aged post =)
