so how would this ATR43G4 compare with my ATR28G3 or a ATR28G4?!?

BINGO glad someone else has a brain !!!

I will pay someone to race with a open face helmet in hail!!! will be looking like massa in seconds haha I'm still keen as mustard, little rain never hurt noone... BUT I'm reasonably competitive and if my shit cart konks out because the motor had engulfed too much water or the chain seizes from lack of lube i will pick up my kart and throw it at the leader as the are going max speed on the straight

best advertising to say why not to get one right there!

They are expecting 14mm of heavy rain and strong winds on Saturday!!! Is it going to get called off?!? I'm all for a bit of fun, but a flooded track is going to be just shit!

if your going to pull it off, see if u can get a hold of nattalotto and have a look at his manifold!!! not like its going to be using it any time soon

I would assume that a R34 N1 head stock would be better than or at least on par with my 89 shitter standard head, i'm still thinking it is the manifold. I remember back in the day Natalotto had heaps of problems with his china manifold and they did extensive modifications to it to get it working right. I dont know if Brockas has done anything to his?!? I agree the boost is all over the shop, ramps hard then creeps and then falls over... which to me points at a manifold issue!!! my t04z run is about 2 years old, still same dyno, same operator etc etc

hopefully a bit better weather than it is atm...

i dont disagreee that the power curves would be similar!!!

im sure driving a 07 car will help a little, getting the brain back up to speed with the rush that f1 would give you... also will help his fitness and neck muscles to no end but no, it wont help him come to terms with the new car... expect him to be fairly slow in friday practise and get faster all weekend

if you were looking at that kind of power i would suggest a garrett 3076r with possibly a twin scroll rear on a 6-boost manifold look up NYTSKY engine build, he is getting amazing response and power out of a similar settup

all 3 cars done by road speed were r32 gtr's with 1:1 4th gear ratios, 4.11 diff gears and very similar rolling diameters (2 exactly the same) the other 2 cars were on rpm... i know the rpm relationship between speed and rpm in the r32 gtr's so i can translate from there... turbos comparison mainly, most the motors have very similar specs

cause u cant tell the difference between a dyno graph in 3rd or 4th gear?

i cant find a twoogle graph in rpm and the ones based on road speed seem to be in 3rd gear (he has a os mission so i dont know the road speed/rpm relationship)

i said pretty much exactly the same thing in the original post... i have accounted for a few things you have listed though tacho numbers are directly proportional to rpm... this graph actually translates 2 graphs from rpm to road speed, i can repost it in rpm if you like!!!

I should add that if anyone wants me to add their own graph (or someones elses) let me know

Just to add a bit of fuel to the fire! I had a bit of time up my sleave and was bored so I made up this graph. Now it's not perfect, there are different dynos, different boost levels, different correction methods etc etc but it gives a decent indication of levels of response and overall power on stock stroke rb26's. Green Line - 2.6L Garrett T04Z 0.84 (24psi) on modded china manifold, HKS 272 10.25 cams and decent head porting Yellow Line - 2.6L Garrett T04Z 0.84 Split (24psi) on 6-boost split manifold, JUN 272 10.5 cams and no head work Black Line - 2.6L Garrett 3582R 0.8x T4 rear (28psi) on china manifold, TOMEI 270 10.8mm cams and no head work Blue Line - 2.6L (the motor from the yellow line) but with Garrett 2860-5’s (24psi) on 6-boost low mount manifolds Pink Line - 2.6L with HKS GT-SS (18psi) on Tomei manifolds with Tomei 260 9.15 cams with head porting Anyways a picture tells a 1000 words (sorry about my shocking excel skills)

keen to see webber take over michael on the last lap with aggressive move to take the win... and hamilton to come last

should have used one off the vl motor extra 15rwhp for sure

only just over 2 weeks away... anyone else getting as excited as a bunbury man who has found a second tooth?

just to let you guys know... the database must be a lot older than a "few hours" seems like at least 1 if not 2 days of posts have been lost

clearly both these runs were conducted in the same gear... the dyno operator has just made a mistake and not entered the right gear into the program you would be ignorant to think otherwise

i always knew he was a queer... tahni is a front!

why run a trust kit with a HKS turbo... for starters isnt the 38gk a T4 flange and the 62R a v-band flange???

very nice power/response... very very nice in fact!!! im a big fan of the 3076r, they are like a baby t04z that could
