Who's Completed A 10 Second Pass Using 2860-5

[monga]

Just interested to see who has completed a 10 second pass using these turbo's. I recently did [email protected] with 1.85ft and was only allowed two passes. However I think there is another .2 left in this setup without using the gas.

10.34 @ 134

1474KG without driver

street tyres

no nos

HKS 2530's though

Dirt, how much power was the car making when you ran the 10.3 ?

[monga]

I think the -5 are great turbo's but I think the 2530's will do 400rwkw+ much easier than the Garrett spec.

[R31Nismoid]

-5s have done over 400rwkw before, and 380-390rwkw fairly easily many times. I dont think one is easier than the other from what the GTR's around here do.

How much power was that with again Paul? that was the 430rwkw?

I'll have to go and read some stuff, but I'm not totally sure 500rwhp and 126mph works out that well.

You should get 10's on -5's without gas

ive given the weight and MPH...so the power level should be easy to work out.

to make it easy it was between 400 and 420 depending on how the engine was feeling on the day.

im pretty sure the day before racing we dyno'd it and a figure of 404 AWKW at 2 bar seems to ring a bell.

Thanks for the feedback.

Shocking 60ft, u dont need power you need grip.

I had a rough idea

Was more for everyone else's benefit

And ye, get a .2 on the 60ft time, that's the 10 second pass done

yeah 2 10ths at the slow end will net 4 10ths at the fast end.

btw..i could easily work out how much power you were making given the trap speed and weight.

Its just that some like to claim crazy hp figures..then trap speed at the track indicates they could not have been making that kind of power.

My previous ride was an aspirated torana that ran 9.5 @ 141...i was just more curious to see what kind of hp guys were making compared to their et thats all...trap speed tells no lies though ,unlike some dyno's or owners.

my car is well known and its power output is quite public due mainly to the car entering dyno comps which are ran under strict conditions. My MPH has always matched the dyno output of the car...the 400m dyno never lies.

The car had made 460KW+ at the tyres with the HKS 2530's but was never ran with that level of boost (2.5bar) at the track.

its funny how some people like to elevate the power level of their car only to be caught out when they run it down the strip. Some of this is often not the car owners fault but of dyno/workshop operators trying to inflate their ego's or abilities. Ive seen it time and time again at dyno comps too when cars don't come near a figure it made at (insert workshop name here) and blame the dyno or operator only to have my car go on and be within a few KW of what it normally makes.

Its a little presumptuous to assume just because a car runs lower power in a comp than expected that the tuner/workshop is inflating figures don't you think?

Sometimes, i would say yes.

However as past threads go, there seems to be a fair bit of 'inflating' going on sometimes

i guess thats better than some cars in perth running close to 500rwhp and trapping at 118mph

126.5mph might squeeze you into a 10 but you will need decent tyres

i think there have been a few 32's in perth that have run 10's at 127mph

[ezy_09s]

I didnt think it was possible to make that kind of power with these turbo's..

Im not doubting you at all dirt ,only surprised that you made 460kw.

I think i will definately be going with a set of these.

Although i am fairly new to gtr ownership..a few guys i have spoken to have said you wont make 400kw or over with the 25/30's .

shows how much they really know i guess.

HKS 2530's though

What fuel??? I would've thought that 2.5 bar even on race fuel would be pushing shit up a hill.

I've seen around 370rwkw with the -5 on about 25psi of boost on a tired race engine RB26 on pump98.

I would like to think that you might see around 420rwkw with race fuel tho.

467 to be precise...done at Powercruise dyno comp...its on the dvd for all to see. VP 104 fuel was used and 34psi of boost...we actually removed the actuator lines and let the turbo's produce as much boost as they could muster...yes im crazy!! ( a few little dyno comp tricks were also used that netted nearly 20KW more than it had ever made before )

the set-up was fairly simple...Full HKS 2530 turbo kit...4 inch cooler...Power FC...stock plenum. The engine was one of my builds with all Nissan internals except pistons, rod bolts and cams. It was built tough and copped an absolute thrashing for 3.5years before the N1 oil pump expired at 9500rpm banging it off the limiter launching at WSID.

I remember the night we cracked 400 at the treads on pump fuel...we thought it could never be done. Then we put race fuel in it and made another 42KW!!...ahh those were the days. Now if i dont make over 600KW im disapointed...

With the sort of boost that Dirt is talking about with a splash of good fuel that power level wouldn't be unbelievable. My own car R33GTR RB28 with 2530's is making 417awkw on 1.4bar (21psi) at at only 7100rpm on bp ultimate pump fuel and the power on the dyno sheet is still climbing so with full rpm 8500 it would be making an easy 425awkw and 2530's dont really come into their effeciancy untill the see at least 1.7bar (25psi) anyone wanting to check out the dyno graph it is posted in my build thread in the motorsport section dazmos R33GTR track car.

Almost all the GTR's here, PULP - 380rwkw... 20-22psi tops. (2.6ltr)

Big $$$ motors will do over 400, and have done

That tired motor wasn't doing many favours, probably needed the extra few PSI to counter the blowby
