Garrett Medium Frame Gtx Turbos

[rob82]

i got before & after dyno graphs on the GT35R & GTX35R...

all i can say is the GT35R @ 112Klms makes 145rwkw

GTX35R @112klms makes 225rwkw

Torque is a much flatter / longer

What fuel? That's good power.

Caltex eflex fuel

7 Year old M/T's

1530kg car without driver

If memory serves me correct 400-420rwkw in a 1750/1800kg car(inc driver) is ~130mph.

Closer to 400-450rwkw does seem about right

Not having a go here either, the MPH is always a good indicator. Video the run at all?

[rob82]

Plug 740 engine hp (which is approximately 505rwkw) into any ET calculator with 3500lb car and your pretty close to 136mph. So I would say the dyno figure is pretty close to 136mph....

Never had those ET calcs work that well because they don't take things like diff gearing into account for one (of the many many other factors).

Have a look @ the drag thread and base it of that & the power associated, it's got specific times to Skylines which is far more relevant and suggests the calcs are not as accurate as what people actually go and run.

Take NUTR33 for example:

360rwkw - [email protected]

Far cry from 500rwkw and already into the 130mph mark.

i got 2 runs in & my first time at WSID.

i short shifted into 2nd & 3rd on the 10.8 pass.

so the mph will rise if we hold out gears longer but traction was an issue...

Traction doesn't tend to have a big effect on trap speeds until it is actually an extended smokey skid

[BMYHOE]

i agreed. it spun 1st gear.. 1.89 60ft aiming for a 1.5 60ft with new m/t's

if we can strip close to 130kg's?

MPH has to rise.

Very true. At the motive DVD thingo last year I did a few runs with the start like I was taking off from a set of lights. Later in it was 8000 rpm launches. The difference? 2 MPH.

MPH will rise, and also fall

A better 60ft (.4 drop you are aiming for) generally will mean a lower MPH by 2-3MPH on average is what I found when racing regularly. Stripping KG will increase - so overall you should be in front though it might not be as much as you are expecting if it hooks up nicely

Cant wait to get back out there

This is on an SR20VE perhaps, but still - I am officially quite impressed with the GTX3076R now....

477kw on 30psi running E85:

Wow 225kw power increase in 1000rpm!!! CRAZY!

[GTScotT]

Wow 225kw power increase in 1000rpm!!! WHEEL SPIN!

FYP Bro

Hahaha may be some slight traction loss!

[Lithium]

Fortunately it is a drift car

[GTScotT]

I can imagine that would work quite well lol

[AngryRB]

yep they definitely lend themselves to that purpose, they love top end high boost and hit hard in the mid range

What's the difference between the two runs?
