Hey There,
Got my rvr running with the new motor and im quite happy with it, making good power...


But....

Its laggy as fook! its making in the mid 200s kw wise but by the time it is hitting 17psi its doing 5750rpm!
I have a kando dynamics td06-25g (it says on id tag that it has the 60-1 wheel in it) and i knew it was large but im running a fairly serious motor (hks 272, cp forged pistons, heavily port n polished, custom plenum etc etc)

Im used to the big16g snapping on boost and away we go but by the time im starting to hit high boost im already off the speedo dial haha
HELP!

talk to Mikey aka evocpe, he has a Kando tdo6 i think. He loves it as far as i know, hasn't had any issues with it... he is running evo final drive tho. To my understanding rvr's have a lower final drive ratio, 57 tooth crown wheel over the evo 62 or gsr 58 tooth which is what im running. I have a small 16g and i dont hit 15psi in 3rd till 4.5 ish that's from wot around 2000. I think that final drive ratios play a big part in how and where the power will come on. Perhaps you should have stuck with a tdo5 20g.? maybe a tdo6-16/18g?

my vote is your cam timing is not set correctly.

im running a PTE 60-1 and have 22psi at 4500rpm or there abouts.

I agree with Craig...

try advancing the inlet cam to bring on the boost lower in the rev range.

Fitted a Kando TD06-20G to GROOVE3's Evo 2 stroker motor recently ( initially using a TD05-20G). Standard cams... The TD06 came on 500 rpm later, but went "ballistic" in the upper rev range of around 4500 -6000rpm. The TD06-20G made full boost ( set at 22 psi) before 4000 rpm and is emminently driveable on the road. In fact, at one stage setting up the boost controller , it climbed to 30 psi by 4500 rpm.... That , on E85, was definitely too much torque for the gearbox LOL ! On this Stroker 2.35 litre motor , I can definitely recommend it. For around town and general driveability, I am stating to think that 264's are the biggest practical cam grind ... Especially since this Evo 2 was still running small cams.

Another thing to think about... are you using the Kando supplied waste gate diagphram ?? Its a bit of a joke at about 6 psi spring pressure. That was the one supplied on our more conventional compressor cover with the outlet facing down ( and not the evo style upwards facing bolt on type . I had all sorts of trouble until I modified the wastegate diagphram... The wastegate flapper was just getting blown open.....

oh forgot to say i have removed the stock internal wastegate and run a tial 38mm with a 1bar spring.

Thing is when my car went to get the run in tune they refused to play with timing, something along the lines that they couldnt get the knock sensor where they wanted t put it and where they put it, they couldnt hear anything so didnt play with timing whatsoever to avoid blowing the motor, so advancing my inlet cam will bring the turbo on earlier? you guys rock!

I wouldnt worry about it till it has a proper tune on it. Have they ever tuned a 4g before, they dont sound that great?

[DOUGMO]

A td06 25g is bigger and heavier than a 20g though, and on a 2.0?
Might still be pretty laggy

[EVL20T]

Im running a TD06 20G on my car, i love it... full boost 15psi by 3500-4000rpm and continues to 7500rpm

Awesome to drive around town and also on the freeway cant wait to dial in the cams and up the boost

Removed or welded shut ?? Subtle difference in the wording , will have a major effect on lag ....

[QIK-247]

Its welded im pretty sure, my mechanic tacked the wastegate flap (i honestly cant remember how it was done)

The guys that tuned it are world known for their engine bulding and tunes, and for that reason i took my car there but they were new to autronic (not to say they couldnt tune them, they just hadnt worked with them)

Problem was, where the stock knock sensor is, there sensor wouldnt go in same spot due to the bolt on the stock one being sizeably larger than the one that is used on their knock sensor...usually you can mount in other spots but their literally was nowhere to put it that would be decent.

Anyone have ideas how far to advance the inlet cam?

[BMGTZ]

advance 2 degrees at a time then.

CHECK PISTON TO VALVE CLEARANCE.....

[DOUGMO]

Gt garage tuning it?

[QIK-247]

nope, they are the reason i had to rebuild in the first place Nick is an awesome tuner but their workmanship on my car was hopeless.

Tuned by Confidyne, they build 750hp 350z motors for offroad buggys in USA, they have a 1000hp time attack 370z, and tonnes of other crazy builds on the way (plus a nice 2million dollar workshop)

Going to modify another knock sensor so it will fit up and then try advancing the inlet cam

[DOUGMO]

Lol, I was going to say they have dropped the ball a bit.

A mate if mine fabricates/ works at confidyne

[QIK-247]

would that be gloze?

Yeah they have dropped the ball at gt abit, 90% of the time i have owned my rvr i have only let it goto nick at gt but having to fix a not so old motor because of poor workmanship (he sacked the guy that did it) turned me off there.


UPDATE: advanced inlet cam 4 degrees and its coming on boost much better, but i think i need a new boost gauge as it now surpasses the 20psi spot lol, oh and i need another tune as it now idles at 500rpm

[DOUGMO]

nah, his name is jeremy, he would be in antarctica at the moment though as he goes between there and confidyne

[QIK-247]

ah ok, i usually deal with andrew lawson and other andrew (manager). He fabricates in antartica?!?

[DOUGMO]

Hes a helicopter mechanic down there but fabricates too, he is a mate of andrew lawsons

[JSTYLE]

if its a genuine TD06-25G then yes dont expect boost any earlier then 4200-4500rpm.
its a lag monster on a 4G63 (2.0)

i personally would of gone TD05H-20G backcut (good for ~240kw ~25psi)
