Would be interesting to see power difference between 122 and 127k. I assume that Borg Warner would have a decent percentage or error in those speeds (say 30-60%) so 127k should exactly be on the ragged edge.

Will be good to see how fast it actually is on the black dyno, I suspect it'll be quicker than the figures suggest

I'll be back when you stop f**king around with that baby turbo and get a 9180 on there, or even maybe a 9174 if you want to be soft 300rwkw at 4000rpm is about double (plus some) power that time makes so it's not exactly like you need that much grunt that low

Has the fluff fallen out of Ernie yet? Otherwise not a real EFR

Going well still... Been through lots of different sets of cams to see what's best and finally arrived at some I think work well. In terms of lap times, managed to drop under a minute at Barbs which I'm stoked about, this was with around 700hp and a bit of mid range lacking, the car now has 766hp on high boost and tonnes more mid range but every time I head to the track it seems to be wet. Probably need a bit of aero or weight saving to keep dropping times but thus far I'm fairly happy with my 59.77sec lap and nothing else is really close so I'll just enjoy it for now and wait for inevitably others to start catching me.

I like how photobucket is now f**ked so all the pics are gone! Winning

Technically it's rear hub hp, not awhp. I don't think they have an overspeed (it's not an EFR after all) Turning the dyno on SAE correction it shows up 797hp so god knows how much it's making at the flywheel but definitely more than the turbo is rated at. Never measured backpressure in exhaust but air temps after the intercooler are more than reasonable

Smooth idle, not even lumpy at all... I'll get a video on weekend

Yup, there was talk about going a 222/222 and that was actually going to push the advertised duration to 226 but drop the lift down to 10mm From Kelford

Secret! I don't think Kelford do 50 thou, but they are 226 at 1mm

Yes, 182R are newest (I think they were actually labelled 182X on the box)... They are custom 260 10.3mm ones from Kelford

Update, the custom grinds ended up working well (although the GREX were still mighty in hindsight)

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

At a guess (4.11s with 265/18s) 112 km/hr is around 4000rpm... So it's gone from 345kw to 230kw which is a massive wack. I've now stopped look at graphs across the x axis for response and now look more to the difference in y axis as it shows a lot more about how a car will drive

It's got twice the horsepower at 4500rpm! That would be a massive difference

I honestly did enjoy the saltyness of the Jem R34 thread because the guy appears to be a bit of a knob... Also so many fanbois butthurt that the $10k manifold and $5k dump pipe work the same as every other one haha

Bobby, Piggaz... Same same

The valve clearances come on the cam spec sheets. I'm fairly sure Kelford clearances are a good 0.1mm tighter than standard and almost certain you will need much thicker shims

Don't take this as gospel as everything isn't totally apples with apples as there were some differences in the head (intake squish removed on the head that had the GREX and 182S cams) but should give you a rough idea. I've now got a custom grind 260 that should be as good as the GREX cams or even a bit better *fingers crossed*

You're in luck as I've actually done a direct back to back with Type-B poncams and 182S Same response but 690 vs 750 hp at high boost... 182S made same power and response with 0.4bar less boost

Yes 182-S Power band shifter too far right for me, I really want/need down low grunt for the kind of track and sprint work I do, it's a 6262. 8374 is similar sized to my 6262 from most accounts so I'd personally be going smaller duration (I've now got 260's but haven't tuned it yet to see if there is a big improvment) If you do decide to go the 182-S let me know because you will be able to save a few hundred buying from me

You'd think your logic is correct but you will end up rendering 1st gear fairly useless and thus turn a 6 speed back into effectively a 5 speed. Put in R34 diffs or don't bother IMO

I have some Kelford split duration 274's that were a bit too big for my set up but perfect for yours if you are interested?
