Test N Tune Mph Vs Hp

[l0WRB]

went to a test n tune last friday nite at benaraby

best time managed was 13.318 @ 107.6mph (i thought a stock 33 with cooler/exhaust/ecu would get 108-110mph) hmmm

60ft was 2.2sec

car was on dyno weekend b4 made just a tiny bit over 300rwhp

car only hit 16.5psi all nite, i was hoping for over 110mph, maybe i should have dialed in a few more psi..

my mph seems down for my power? anyone?

Should be around 110-111, thats what i was running with 220rwkw.

And being a stock turbo wont really make 220rwkw in the real world... Your MPH is right for the power of 200rwkw, which is what the stock turbo makes

(270-275rwhp)

MPH isnt down for the power, its just showing your reading was probably a little inflated.

[l0WRB]

im running kkr480 with link ecu and 600cc injectors dude,

only rolled up 300hp cause intake temps to hot and tuner said he has knock control on and as he added timing link would pull it back out like 6 degrees at a time, i know my hp is down, but dyno readout is on a very old dyno, known to read low and has never been calibrated in the god know how many yrs its been there lol

my mates r32 came up with me, he ran up 13.4 @ 116mph

mind u traction was a joke, track had dirt and rocks all over it.. hmmm

but like u said i was expecting around 110-111mph which is wot i was thinkin hmmm

i raced 2 skylines there on the nite, a silver 33 with cooler exhaust etc and a r34 with same mods and i absolutely smashed them specially thru top end

so i dunno wot the go is hey grrr

my mate who ran 116mph he was hitting limiter in 4th going over the line, and last time it seen dyno it was around the 400rwhp mark

[Granthem]

Hehe that would be my 34. its got cat back. thats the only mods it has. i was doing 2.6 60fts... couldnt get any traction or it would bog.

i ran 93mph dude and thats holding 6psi boost. just to give an indication

the r33 was running a garrett gt3017r i think, front mount, zorst, boosted to around 8-9psi i think. he was pretty dissapointed i think.

But yeh im dead stocko to be honest matey i was expecting to get wasted hehe. love how low your car is. plates definitely apply

haha awsome man, your car still went alrite lol yeh i would launch at about 4000rpm and it would just bog and then lagg lagg then boost haha..

me and a mate were both racing my car, yeah that r33 went alrite then i would just reel him in top end... where r u guys from? gladstone?

we are from rocky. Im generally there most meets with either my commie or the r34 now days.

My coil overs led to bad wheelspin. abit hard i think lol. Could spin all first after a bog down and coming back on boost, then all second, chirp 3rd and chirp 4th over the line. dunno how it did it haha stocko clutch wasnt expecting it to hook up so well!

yeh its a base figure. my times were terrible but due to the launches. but im just aiming for 100mph with a full zorst and up the boost to 12psi. close to 100mph anyway. and hopefully a high 13 with a good launch.

I ran 113mph with 300rwhp

Well either way you dont have 220rwkw/300rwhp far as i see it

limiter in 4th at only 116mph doesnt seem right. whats his limiter set at? must be only like 6000rpm?

Some answers;

Was the dyno run for power done with the bonnet up?

Do you have a pod filter without a heat sheild?

If the answer is yes to both I think you are experiencing less power on the road/track then you see on the dyno.

Also the KKr turbo's tend to suffer a little from lag, resulting in lower average power. Average power is king not peak power. Robo's HKS equiped car with 300rwhp would have had a notably fatter power band than your KKR making the average power higher and the car faster over the 1/4 mile (with a higher terminal).

For comparison my 175rwkw r33gtst ran 13.3 @106mph on a fairly hot day with a 2.3 60ft. Stock intercooler/turbo(10psi) and ecu with S-afc.

With a stock ecu and that turbo you might be asking for trouble given the timing map would be unsuited to the KKR curve. Probably worth getting a S-AFC or an ecu upgrade soon.

its running a full replacement ecu already LINK ecu.

i think i need to get car redone by a person who knows link a bit better i think. hmmmm

Maybe not.

There could be other issues, like a blocked cat.

Do you have a dyno with AFR's to post up at all?

speaking about cats,

about 2 weeks ago i pulled my gutted 3" cat off and put a stock 3" cat back on that i bought from a member from sau..

only done it 2 try and quieting down the exhaust as its loud as.. but hmmm

no sorry i dont have a dyno printout with afr's, but i can asure u its gettin clean afr's

tuner only added around 5 degrees timing over standard,not sure how it works but thats wot was told to me wen i was watchin him, but link would pull out timing as soon as it gets 2 much knock.

A stock cat! There's your problem, no doubt it's a second hand one too.

[zebra]

Adding timing?

no wonder it was knocking!

Btw as my sig says I ran 104mph with stock turbo and dump.
