lmao well if 21psi is 95% of a td05's safe running condition then my old td04 musta been special haha, cus i ran it at 21psi for quite a while and boosted it everywhere lol td05s can handle 2 bar cnt they?
Big power starlets are nothing but a pain in the arse

so by whats he saying a td05 is not bigger then a td05 then.lol
i do believe that 1.5 on a td05 means its in its efficeny range for that turbo.
anyways this is at captain starbo, what boost levels u seeing comapred to ur td04 with ur td05 throughout ur rev range??

the problem was a split pipe guys read the thread. ^^
as for the 21psi being low boost @ThestarletGT nobody is saying it is low boost. no body is saying that it relates to the turbo having the potential to run 90psi.
what people are saying is that the turbo can run safely at 1.5bar for years without problems tired and tested and that almost 2bar is often used(and more) on this self same secondhand turbo units for drag or track use where reliablity is less important.
1.4bar on a td04 would be seen as the upper limit though i recall Gaz telling me when he was over that his 4wd gt ran 1.6 or more on the strip.

erm actually no rally car runs a BOV and the reason behind this isn't to do with responce or anything else, its down to homoligation rules. BOV's were banned in WRC back when group b was banned and went to the 300bhp rule, same time they brought in the 51mm intake restrictor
and the chattering is from the wrc car your almost correct, its just not out the BOV (as its not there) and it sounds different to normal surge we hear on the road because the antilag is keeping the boost up instead of it just dieing off when you change gear so its a constant surge because the antilag keeps it spinning at full speed.

Maybe its a matter of language barrier, here. We use FIA rules here for GrpN (32mm) and GrpA (34mm restrictors) and all those cars have blow-off valves, either factory or FIA homologated. We have serveral WRCars and have had tons of ex-works GrpN/A cars here and all of them of blow off valves. The newer cars have a computer controlled BOV (or a device that functions similarly) that returns to the system. There are generally three noises the wastegate chatter, the bov coming through back through the air filter, and the anti-lag.
I realized that on that side of the pond a Dump Valve and a Blow-off valve are not necessarily the same thing.
Having run two GrpN Lancer Evolutions, they used both used factory BOVs, the recirculating type.

sorry i wasn't talking about group N or A. i was talking about some of the 80's proper rally cars, i know for a fact the Armin swartz rally de corsica celica st185 doesn't run one.
Only try of pressure releace on the boost pipes is a feed into the exhaust for the airfeed on the antilag, but still not enough to ellimante compressor surge.
What else would you class as a dump valve and blow off valve? same thing as far as i know.

will admit where i made a mistake, its a 34mm restrictor not 51mm. memories fading in my old age lol

I'm quite sure that today's rally cars are just as proper, lol! Rally turbochargers aren't meant to last. They generally are replaced on GrpN cars running anti-lag once a season here, so survivability isn't a priority. There is an article in DSport Magazine on Ken Block's car that covers the turbocharger.

dont think so, sure a td05 is the same size as a td05 lol.
he is running 1.5-1.6 bar.
i believe he bought a shitty turbo, and it gave up,(as did the first one) unfortunately this time, a burst boost pipe showed the same symptoms, and a speculation was made, that another turbo had gone, before finding the burst pipe.
oh, and ive got a dump v/v. tdo5 @ 1.7 bar. so i guess, for the first time in my life, im not the "idiot" hehe.

i was just refering to the good old days of rally with the classics
they didn't have bov's on there cars then because of regulations.this man knows his stuff, why do people continue to question it, everything he said makes complete sense.

Yah know I sort of agree with you. I did think rallying has fallen off recently, but once I started watching the IRC I realized that the talent has just shifted. The WRC just became too expensive to run for the average joe and a lot of good drivers have found themselves in lower or alternate ranks. I am a big fan of S1600 and S2000 cars. I do miss the turbo noises and the flames, but the level of competition with such good drivers makes up for it. Seeing a Kris Meeke fly down a stage is just breath taking.

Couldnt agree more. A well tuned, big bhp car is no different to say a stock car (bar the obvious stuff like the clutch, breaks etc)... My ep as is (when driving decently) wastes alot less than when it used to have that dreadful ct9.
Its true that sometimes the divine powers start to pick on you and send wave after bad wave of bad luck... but thrust me mate there always is sunshine after the rain

think they should just bring back group B Imagine what they would belike now if able to run unlimited

It would be crazy given the modern advances. 1000hp fully carbon fibre beasts. I'm not sure the modern driver could keep up.

Can't see it being a good idea TBH. As Rory says, the drivers are nothing like they used to be. The bodycount would be heavy lol.
