So did you get the one with the 1mm hole in it? Thats the best one is it?

I have a turbosmart manual boost controller I scored off a mate, are the Turbosmart ones better then the $25 item?

[markimak]

im finding the holed one to be more stable on boost and slightly more laggy.

will see on the R34 tomorrow..

[SS8_Gohan]

i thought you said the holed one was slightly more responsive, but more erratic at high end rpm?

and no-hole was a touch laggier, but more stable?

[markimak]

opps meant the holed one spiked little bit non holed no spike but slightly more laggy lol..

How do they compare next to the Turbosmart item?

Is this type a bleed valve boost controller? Because if it is I would say the ball and spring type would be far better.

A couple of pics installed on my MR2. Not sure if its right but...seems to be spiking. Could be the way i sealed off the stock solenoid lines.

Hey,

I just got my turbotech controller from Mark off of ebay (whitie_bear on ebay) and my controller doesnt have that tiny excess pressure hole drilled in the back like this one does!!!!!

Isnt that going to highly affect the performance of the controller, i have tried to contact Mark but still no reply, im sure he is busy but this is very annoying to me!!!!!!!!!

Are you sure you even brought it from Mark? When I brought mine from him his eBay name was simark87? Mine does not have the hole either and it works very well.

[SS8_Gohan]

hole or no-hole better/worse is still up in the air a little. If it works good on your car, great. Go with it but don't write it off just because there is no hole. Try it first.

i drilled a 1mm hole in my mbc and i have noticed if i accelerate slowly but still let the engine rev right out boost will slowly climb up to 15-17psi and hold there but if i smash the loud pedal staright to the ground boost will shoot up to 13psi and hold there.

got me confused...

[markimak]

anyway.. mine is set on the GTR to 10psi and its feels pretty good. its something like 9.5 but spiking a little.. full boost earlier..

still waiting for the S14a to come round and install on that

also has anyone had an issue with this controller..? eg. overboost dramatically.. clog up..kill turbo? etc?

i've never had an issue with it. it always holds boost perfectly.

there was one stage where i had heaps of lag, but that turned out to be my cat. changed it, problem solved.

i'm still happy with no hole. since there's no lag, and response is super quick, i'm happy to leave it alone.

so how did u find hole vs no hole? did u do the r34 yet?

[groper]

rather than reading back thru 72 pages, can someone who has already read them let me know if its worth running them on r33 GTR at 19psi?
