There's Morpowa, no residential houses along that street & pricing should be around the Tilbrooks range.

You almost had me? You never had me you never had your car... Granny shiftin' not double clutchin' like you should. You're lucky that hundred shot of NOS didn't blow the welds on the intake! You almost had me?

i would hope to think there cheaper than Tilbrooks and i dont think skylines would be much louder than revvy toyota's but would have to ask shaun what he knows he can get away with

i think on said night we could all put in maybee for pizza pie and cokes wot ever your poison

[J_Red33]

try and find my extra 20kw that i lost

my extra bits are

BP: 101.3 RH: 60 AT:25 IT:39 RR:013 TN:3.454

Steve didn't they say your car was leaning out? Or was that just Seans car? Maybe your fuel pump is on the way out or you need to start using 98 octane.

Interesting the IT temps are consistent.

Didn't feel like 40degree air inside there. yer was warm but not 40.

Was shaun placing the sensor on the pods/inlet snorkle etc I can't say I looked.

Yeah I did notice Shaun was placing the sensor in the snorkel.

Still surprised that my IT was 49, heat soak, a hot engine & maybe a bad fan position too is the only explanation I have.

yeah my last dyno run when i got 175 it was leaning out but on sat shaun said it was fine

i need to book sum time with him i think

From my experience with dyno's its more your rear tyres getting to hot that drops the power/ torque on the second run then heat soak.

If you sit back and think about how much load is placed on your back tyres as there screaming away on a nearly smooth metal drum. also when you add in the fact that shaun straps your cars back and down, in my eyes thats pulling your rear wheels away from the front roller. how are you supposed to get good power to to the dyno with out getting up on top of the front roller for maximum traction?

the only proof i have is i was with a friend at boostworx a couple of months ago and he was missing 56kws from the previous day on a different dyno. i felt the tyres after just one power run and they were slimy, and way to hot to use so we left.

on the other hand hitek dyno straps your car very differently. the further your car goes forward the harder its forced onto the front roller, and you get consistent runs.

the other day i was on there for over an hour and as we made changes the power kept rising.

once i got to final reult we ran it up twice and both runs were within 1 kw of each other. yet the back tyres were still gripping stong and weren't slimy at all.

end result 317kws.

He also uses a laptop for tuning the power fc.

[Rolls]

both of my runs were .4 of a kw different.

[J_Red33]

The main reason I got such a major power drop I think you will find is due to the fact I've still only got the little side mount intercooler & mine did put out the highest amount of power out of the 33's with the stockie. Many were actually pulling more power on their second run & they had a lot more at the wheels than me, somehow I don't think 177kw is enough to trouble their dyno & I do have some 265's on the back so pleanty of grip.

Both runs were done simitaneously & when you look at my chart torque was dropping off the whole way through (it jumped up when it boost control went into high mode but started dropping off even quicker thereafter) so by the time the second run was carried out my intake temp at the plenum would have been nice & toasty.

I'm sure if I get a beefy front mount fitted the readings will be much more consistent, not to mention higher.

i didnt think fmic = more power per say just means u can wind the boost up more and that = more power if u run the same boost after the FMIC goes on you should make the same power

[Maxx]

cooler intake air = higher density of air get burn = more power

[Madaz]

ah ok so should creat 5-10 more KW depending on density of the air said cooler provides

Shaun owns a datalogit. He prefers to use the hc as its faster for him. Using the lappie is personal preference and is no different to using the hc. It just enables us to data log, and change a few other settings when u run out of resolution etc...

he was missing 56kws from the previous day on a different dyno

Its about consistency. Dont go from one dyno to another and expect it to read the same. Shauns dyno is know to read lower than others.

I was more concerned by the temp of the tyres.

on shauns dyno they were melting, on the other dyno they were fine to touch.

next time you run your car there feel your tyres!

it maybe the reason why his dyno reads low....

[S3_Girl]

If you strap it loose and let the tyres up on the front rollers,

you will get a higher reading:), this trick has been proven many times

in dyno comps before here and interstate. You can apparently also overspeed the dyno by getting it

up on the front roller and let it wheelsping hard on it and get a fudged figure aswell with big power cars

I'm confused, why would you get more traction on the front roller, there is more surface area when you car

is on both rollers! the same reason you tyres get a lot hotter! they are actually touching something!

I dunno about you guys but I don't think Shaun's dyno reads low. It seems on the mark to me. But interesting about the tyres being warm. Its an indication that there is excessive friction.. either being strapped down too hard or not enough?

[kralster]

well i got 157 kw out of a bone stock r34 so it's seems pretty well on the money to me.

[DriftR_33]

9 months ago i ran 195.2 last saturday i ran 197.7!!!

ohh and my tyres were smooth bald!!!

[Madaz]

my old mechanic told me u can also run brake on dynos and sum tunning places will wind the brake on for your first pass pretend to much arround with your car then wind it off and instant more KW your happy and they get paid

[mr_rbman]

thats the first time i've heard that about the tires, its interesting to know, i think you guys need to try and stop reading into these figures so much. Remember a dyno is only a tuning tool, the track and your MPH is a real test of the power your making and until we get a track we won't really know i guess! Dyno's can vary so much with their power readings just from the tiniest things, its nothing to get caught up on!

[EnricoPalazzo]

i dont think u can apply a percentage of brake to the dyno, it would damage it while trying to apply brake at load, so sounds bs to me.
