Kando Dynamics Turbo

[Rolls]

If the motor is happy revving there then I dont see why not. The torque and power character of the setup would influence the load on the motor, there is no denying that. It just might be as happy spinning to 8 as a different setup would be spinning to 7.

The forces created by an identical stroke/bore motor revving to those speeds is identical if all the same parts are used, the torque is obviously different though.

I guess what I was getting at is 8.5k is getting very close to the limit where stock rod bolts etc let go if held there for extended periods of time.

my r33 will be going back into trent(status) soon, hopefully before christmas. my t67-25g setup has been proving very good, no issues yet except for my gearbox. trent, if you read this the gearbox shit the tin 2 weeks after the dyno runs so im going to guess it was slipping when tuned, and also the converter is a bit spongy and needs a rebuild(checked by knox automatics). ive been told the solenoids are fkd, the clutch drum for 3rd/over drive is worn out, and the band needs replacing haha. Anyway, i have just bought myself a fully manualised ford c4 street strip box brand new from rocket to go into the car, along with a 3000 stall converter, and a b & m megashifter. i have changed i/c the pipework again since the last tune(only made 255rwkw) and planning on going 4" inlet and moving the afm into the intercooler pipe. ive also heat wrapped the exhaust, sorted out the manifold flex issue and bought a turbo blanket. hopefully this time round, upping the boost to around 20-22psi i can make the 300rwkw i was hoping for.

looking forward to your results.

what other mods do you have?

inj/manifold/gate/ etc.

Goodluck with the C4 man!

My brother uses one in his Sigma but its a bit rough for my liking.. Not a brand new rebuilt job just a used one with a stally and shift kit.

Personally I would have gone for a 4L60 (turbo700) but thats just because im scared of hard shifts lol.

How much did the prebuilt C4 set you back and rekon it would be any good for circuit work or drag only? Shift quality I mean.

if you look back around pages 25-30 of this thread u can see my original build. but yeah, all suporting mods, 700cc inj, walbro 255lph pump, stock intake(this is for testing atm, no-one else has done a setup with the stock plenum and this turbo as far as i know), XSpower highmount - wouldnt suggest these, on a hot run, the manifold buckled and needed extra bracing, umm power fc,3" mandrel stainless exhuast all custom made, z32 afm, blitz suspower pod, 44mm gate, turbosmart plumback bov etc etc. i might change the injectors before a re-tune aswell, they are only flowed stock injectors and i dont know how good they are.

cant say how much i paid for the gearbox , but you wouldnt get change from 5k, but it depends on what version you buy, there is 3 of them.

[dori34]

what brand gate are you using?

any plans to upgrade exh manifold or will you still be using the XS power item ?

[OMY31T]

i will put it back on the dyno with the manifold its got for now, the gearbox has kinda chewed up the funds i had ready for buying engine some nice spool internal engine parts, and replacing things i had problems with haha. but i will be changing to a 6boost in future, they are proven items and worth the extra cash. the external gate im not sure what brand, i bought it from the USA for about $150 aus + post, and surpriginly, ive had no boost creep and it holds shut until right on 17 psi, so its doing its job none the less, although im taking the 17 pound spring out, and putting in a 12 psi and going to run a dual stage controller so i can turn it down on the street.

Running that little boost will test out the wastegate's capabilities

how does that work??

[zebra]

needs to bypass more exhasut gas through the gate...

In very basic terms low boost = big gate

lots of boost = small gate

[ARTZ]

ahh yes..makes sense now..

[OMY31T]

certainly will, wether or not i run as low as 12psi im not sure of, being 44, it should be capable of running as little as 15psi, i just dont want to be running a min of 17 all the time and up to a max of say 22, id rather wind it back to a tidy 220rwkw for day to day driving if i can.

[zebra]

bah,, pansy...my BW setup will have a 2 bar spring in the gate lol

[ARTZ]

Is that on a stock JZ zeb??

my gate came with 7 different springs rated up to 25psi..

thinking I'll just get target my boost with springs and not worry about any controller..is this a good idea??

what are the disadvantages (if any) of not running a boost controller, apart from not being adjustable on the fly...

[zebra]

yeah Stock 230,000k old 1J lol

on an external gate setup there isnt a huge advantage to a bleed valve, but an EBC can be setup to bring boost on slower if needed

[OMY31T]

whats the point of having 2 bar on the street? roads are not made for racing, nor good handling, ill keep my 300+rwkw for the strip.

[zebra]

it will only reach 2 Bar when my right foot tells it too....

Might interest you zebra, hes pretty close to tuning now I think
