Wastegate & dump valve questions for an HKS T51-R KAI turbo

Quote from: Grant Monkhouse;754828How is the 1.7 bar testing going Peter? What\'s the RWKW at now?

Good
&
LOT\'S !

I should elaborate, the power is such that now on the Exeddy twin plate carbon clutch if there is not enough heat in it you can feel the clutch slip on power applications in 3rd gear.... it has massive mid range power (and tq) it\'s lots n lots of fun to drive :driving

Power is around ~550bhp? :2Confused < though its very broad, as broad as Fergies ASS, there is lots of it everywhere :2Confused

Quote from: BlitzBoy;754821I ran NO bov on my T51R for the last 4 years no problemo, BOV on big shaft car turbos waste of time especially if the front housing has a ported shroad

Total waste of time on any turbo in my experience, but am just repeating what I have wrote in many other threads on the topic.

Great comparison! Ferries got a great ass.

You must be going through water at an exponential rate now?!

It can suck down a fair bit, but as I try to explain this to people who have maybe not driven a true supercar beater ........... it just accelerates so hard and so quickly that you are doing warp speed in just a hand full of seconds :driving so you find you are not on HYPER power for massive durations of time, so its not using that much more fluid *if that makes sense*

I take her out for a "spin" every weekend and I still can\'t believe how it forces your body into the RECARO, it literally "forms" you to the seat shape :Laugh it\'s unreal, you can feel the G\'forces through your chest and spine :2eek highly recommend it to all who have not been a powerful road rotary that can translate power to pure performance :King

Quote from: RICE RACING;754786BOV = absolute waste of space and time on a turbo car BTW :WaveBye save your ca$h and buy other parts and don\'t waste it on sh7t you do not need :Thumbsup!

1.7bar, no BOV cause its not needed, but hey I\'m a Mechanical Engineer so what would I know right? ..... :spank

Interesting to hear that - I just put a Blitz SS on my FD, and it was a lot of hassle having to get custom pipes welded up. After installing it it would either .... out boost or hardly \'dump\' at all - it\'s now come off the car, and I am back to using a straight joiner instead. I\'m unsure as to whether to bother trying another or not..... :mad:

Honestly they are nothing more than the classic "add on sale" for a workshop or a business, another bit of snake oil to glean money off unsuspecting people who have no idea of basic physics.

BOV\'s are trash, not needed on performance or racing cars period, save your money and buy something that will give you power on a rotary like a good exhaust system, or CDI ignition, or T04 Turbo, or water injection

^ OR ALL OF THE ABOVE ! One thing is for sure you sure as hell do not need a dumpster valve :Giggle they are far more hassle than any "proclaimed" benefits they falsely claim to deliver. :Talking1

Well - already got the t04 and the exhaust. No WI though....:Talking1

Cool, just the wastegate plumbing required then. Any more tips on that - is it better to give it a separate exhaust (if there\'s room) or having it going into the main exhaust as far down the pipe as possible?

*PICS of how to do it* :3gears-rh

After lunch Finished cut out of hole & welding of WG pipe

what ever you decide, please get it remapped for more than 0.85 bar of boost, its like keeping a race horse in a shed, its no where near its efficiency zone, it needs to blow ..... Then you wont need to worry about the odd bit of power or time lost changing gear with or without a dump valve.

AGREED!!!!

i cant see the connection, but very nice..........

^ Boost = wide/broad *lovable* power curve = just like Fergies ASS :Ladys-man

Some nice work there - did you do the exhaust manifold yourself? :god
