Why 185 is a nice crusing speed :thumbsup: haha

But yeah what Ferni said is that I want to know "i think he means with standard gear / diff ratios, 5th gear, redlined (~7000rpm)?" Forget power just assume you had enough to get there!

From what i remember when i tried to figure it out myself i was doin 70 at 2000rpm and 110 at 3000rpm it seem you increase 40kph per 1000rpm (in fifth gear) from that at redline (7000rpm) theoretically you would be doin close to 270kph. i recon your gonna need a fair bit of power to get it there though.

Hey why not just try it for yourself go for a drive see the difference in speed for an increase 1000rpm then see how fast your going at a set rpm and add the difference you worked out earlier for every 1000rpm after that until you get to redline, that should give you a theoretical top speed. If that makes any sence.

man... i top out with the speed limiter at 185km/h in my GTT ... but i wont be doing that again. The car doesnt feel too good when it cuts out... and thats with the car stock as a rock... driving with no shoes .. just socks

yea yea.. i know its a poor attempt at rhyming

I know what you mean. It's a harsh cut out. Scared the crap out of me the first time it happened. I hit it almost everytime down the straight at Eastern Creek the other week. Only just though; car is pretty much stock at the moment.

I took mine to 7000 in 5th with a 4.3 diff. The speedo was obviously back at the zero but it's pretty easy to calculate.

If your doing 120km/h at 3500 rpm then your doing 240 at 7000. But, not many speedos are that acurate at 120km/h. especially when you change wheels, tyres, diffs etc.

Either way, if you get caught your F!@#$ed

Last week before i sold my GTT with HKS suspension... did 200km/h easily and i can fell that there is MORE HP in it.... 250km/h 70% sure that i can reach for my previous R34GTT... anyway

Below is the car i have drove over 200

stock honda civic 1.6 vtec can reach 220 km/h... max out

Stock Mercedes S280 = 220 kmh still have some room to go but i fell like it is flying

Stock UK spec sTT supra = 230 km/h ... easily i am sure it can reach 250KM/h

Basic mod MR2 Turbo= 245 KM/h almost Max out

Stock Alfa romeo 1.7 L = 200KM/H max out

basic mod BMW 328 = 240 almost MAX

Satria GTI = 230 KM/h almost MAX out...

Base on those car above i am sure you guys can judge out have fast can a GTT GO.

    • I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.
    • Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary? 
    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
