The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

So this turbo is similar size to a gt3076r going off of the numbers its putting out?

It has a higher power rating than the 3076 I think... Yet still spools as early (well actually earlier than mine but thats different)...

Kurtis I don't like you any more, you have more powers than me :(

Nah just kidding :thumbsup:

Bump your boost up to 22psi like kurtis is running and it'll probably make close to it, its only like 6-7kw...

Does it make decent power still on slightly lower boost (19ish) or do you need to run the higher boost to make it meet its potential?

Yeah I'd love a better exhaust to get that extra power but I'm pretty happy as is, BUT mine made it with the screamer, so Kurtis probably has more left....

Awesome result!!

Both setups made very similar power at lower boost levels, 19 is still around 340 I think

Makes it sound like like it'd be an interesting comparison with a Forced Performance GT3076R-HTA - the slightly improved spool over the GT3076R isn't surprising given its for intents and purposes a 52trim 76mm compressor (like the GT3076R-HTA) with the advantages that can come with billet goodness. Wonder what the PT5558 could do on full kill, though to start with its well proven its worth by matching the GT3076R in power while spooling better.

yeh, for me its definently proved itself as a good option for people wanting something a little different than a 3076r. Do they make twin scroll turbine housings for the 5558 or is that only for the larger frame turbos like yours Jez?

Nice, twin scroll then? With that setup the 1.15 probably wouldn't have been a bad idea, but that is still going to kick all kinds of ass.... I'd put pressure on and say I'd like to see it hit 600kw ;)

When is it going on the dyno?

Yeah Twin scroll. It feels fairly towy atm with it just running off the gate at 14psi. Will be very interesting to see how it compares with the old HKS T04Z. As for the tune just have to wait & see when mark has the time to come down. Hopefully within the next few weeks.

Pulled 604Hp at all 4 with T04Z on 24 psi So yeah Cant wait to see, Noticed the precision turbo is very Quiet which is a good thing I reckons.

      I did not go to GTR Festival. It's quite a long drive and the car wasn't dialed in yet. I also wanted to see how the racing portion went before going. From what I can tell the classes were not heads up, index, or bracket - just whoever has the quickest ET wins. Never heard of that sort of thing before and maybe some people like it but it's not my cup of tea. I don't suspect I'll go if that is how the racing is done. I did get the car out three times and had issues each time. Some were my error - haven't raced the car in over two years - and others were parts. Had trouble getting the clutch to slip correctly and remembering how it was set up in the Haltech. Broke some drivetrain parts as well that couldn't be fixed in a couple days to get back out. Season definitely didn't end the way I wanted but at least the bearings are still fine! Not a fleck of material in the filter. Really hoping next year is the year I can actually test this car properly.

      find it funny everyone claims different fuel chains, do different things with their fuel blah blah blah. We don't have that many fuel terminals in Australia. The fuel tanker trucks drive into the terminal, fill up, and drive directly to the service station and dump out. The majority of fuel you get, is coming out of the same terminals. The variation is actually at the individual service stations and how good their tanks are, as well as how much turn over they actually have. Older fuel stations, that haven't had their tanks replaced are going to end up with the worst fuel. Also a lot of older stations have shit design, and shit maintenance, and end up with more water absorption into the tank. This is when you then get a bad batch of fuel. Other shit things happen, like tanker drivers have a f**k up, and starting to unload the wrong compartment on their truck into the wrong tank.
