Mph Vs Power

[34GeeTeeTee]

Was that on JEM's dyno? Man, I'd love to see what Mat's thing would run - even just mph, I would guess it'd be near 130mph

I'll get it there soon enough!

No Point in starting a new thread so I might as well use this one.

I ran at Calder on Friday night and the best I could manage was consistent 12.6's on shitty tyres and old tien coilovers that are as hard as a rock. MPH averaged between 108 and 112.

My car has dyno'd at 325 rwkw and it's a full weight 32 GTR.

What are peoples opinions on the low MPH?

I'm considering stick it back on the dyno and maybe checking for some boost leaks?

I would simply say the dyno is reading high to begin with and if there is a boost leak that the tuner didnt pick up on dont go back there. How much boost were they using to make 325rwkw? and what turbo's? built or stock engine?

I have a mate that has that much power and runs 11.3 at around 128mph so there is most certainly something not right with what your saying

[zebra]

As a reference I ran 106mph with ~190rwkws in a 33 Gtst

[gtr jet]

Well the car was dyno'd around 18 months ago so anything could have happened between now n then.

The car is running 20psi on -7s with a built motor.

Either your mate has a completely stripped car or he's making more than 325rwkw in a r32 gtr to run 128mph.

[ido09s]

complete car, no stripping of anything at all, not even the ppare wheel. The car drove to the track, ran on Bob Jane All Rounders, and drove home

Only internal mod is some Tomei drop in cams and cam gears. Daniel has had heaps of runs and knows how to get the thing off the line

Here it is a many years ago, pre cams, against a 32 i helped build that made 460rwkw. Skip through to about 6mins 45, its the one that does the burnout

Can I ask what turbo's those runs were done on?

One thing that slowed me down was hard suspension and low profile tyres but that shouldn't have hindered the mph so much.

[ido09s]

I cant remember now, its years ago now lol

But they were N1's or the equivalent

Sounds like there is something definitely wrong with my car then as I should be running 120mph +

I guess it's time to stick it back on the dyno.

That does seem low mate, the MPH that is. I would have thought at least 118 to 120 and into the 11s with 325rwkw.

Is it a hub dyno or roller? Can you do a power run elsewhere to get a sense check?

[gtr jet]

It is low and the car does feel a bit sluggish with the foot down.

It was dyno'd at Racepace so roller. I guess I could take it to another dyno but I think I need to find out what the issue is first.

10mph up on last time! Weapon! Nice work

[NXTIME]

should be in the nines with that MPH

[XKLABA]

R32 GTR full weight + some for stereo and me and I'm 100kgs plus

265/35/18s 291rwkw = 11.36@125 mph 1.78 60'

Toyo TQs 293rwkw = 11.13@123 mph 1.59 60' with a few kgs removed, from car not me

[XKLABA]

should be in the nines with that MPH

Or very close to it, especially with a 1.68 60'

What tyres ?

[Royce]

M&H Race masters, 245/45/R17

They are a bit old and I think that new fatter Tyres would help get the times down, as I had to be gentle to get it out if the hole, but ill definitely be back to have a crack at a better number

[NXTIME]

get some 275/45/17 drag radials on it

[Royce]

Yeah might give them a go soon might even have to loose coilovers if I can't get traction sorted.

[r32_rb30det]

this is what my r32 gtst with a home built rb26/30det t78 turbo and a chipped ecu rb20det box two

street tyres street driven and my daily 386rwhp 14psi

did a 13.4 at 111mph with wheel spin and no lunch

[Granthem]

I'm supposed to have 250rwkw in my 33.

Have done a 12.9 @ 111mph. 2.1 60ft I think - something shocking anyway.
