Found 1 or 2 now, all seem to die off at around 5000rpm, despite making good power- Is this just the way it is on stock cams? It's not valve floa or stock intake it seems, so presuming it's just a given on stock cams...?

As title. Maybe I'm blind/stupid, but I can't find any? I was determined to stick with N/A for my engine, and tbh watching vids of turbo 1UZs seemed to reinforce that as they all seemed very flat, despite the power levels, but that may just be the videos. So, does anyone have any dyno...

Maybe I'm blind (it is 34 pages, so it's possible) but I didn't see any dyno sheets? I'd love to see as I'm semi regretting this N/A idea already. Peak numbers I know are good, just wanted to see how the power and torque is through the rev range.

Update---- Kelfords finally got back to me, they don't "think" the cams work on stock pistons, ie stock valve cut outs. Anyone know anything about this? Can stock pistons have valve reliefs machined at all? Is it needed? Or is a set of forged my only option? I really don't wanna go turbo, but...

Got the cash for the cams now- that plus this thread makes me feel like a kid at Xmas lol. Are kelford off work until new year I guess?

I'm 'trying' to stick to a budget, so stock pistons for now. Until I can be 100% I want to keep it N/A I better not change the compression to be honest.

Lopey idle and strong midrange. Sounds damn good to me man :)

Merry Xmas all. Here's the cam card for the 207Es they suggested... http://www.camshaftshop.com/uploads/Shoppingcart/207-E.pdf They advertise them as an expected 3000-7500rpm power band, and while midrange performance is something I really do want still, it doesn't need to have tons below...

Great info, thanks! I actually meant 400@flywheel- I knew I had no chance of 400whp- Sorry, in the UK we're still used to using BS flywheel figures and I forget sometimes when posting on forums not based in the UK! By the sounds of it, I am probably best off sticking with the setup as planned...

My current thoughts are IF what we are building isn't enough to keep me happy (It's going in a ~900kg car, so 400bhp should be fine) then I'll get some plenums made and a pair of small low boosting turbos will have to be added. Even if it only added 50bhp up top the torque increase from turbos...

Good info, thanks, and yeah, it didn't look like much could be done to enlarge the port really, so expected it to be mostly around the valve guide. Am I likely to hit 400bhp with my spec? The cams Kelford reccomended are 286deg, 9.9mm lift btw. I'm waiting to hear back to see if skimming the...

Uprated valve springs are on the list in the OP. Not whinging, just not found anything much on here, lots of talk but not much proof/details, especially N/A. Even the link posted wasn't much use. I just imagined there to be a lot more info about than there is, obv' people have done it, but not...

It doesn't seem to work too well as I've found very little. Has anyone had N/A results on stock heads with cams they can tell me about? I don't want to spend big bucks porting heads, and fitting high comp pistons, but I also don't want to be disappointed and end up going turbo not long after...

Regarding the head work- It didn't look to us like a whole lot could be done (without going to larger valves)? Regarding cam wheels- Err, how? There's only one cam gear per head, and the other cam is ran from cogs in the centre of the cams?

ok, can anyone tell me of a forum where people actually know about 1UZs? there must be one in the world?

As title really. Have a 1UZ being built at the moment, and the current plan is to stick to the stock bottomend (but rebuilt), but with Kelford 207-E (286duration) cams and uprated springs, 8 throttles, aftermarket ecu, decent headers, etc etc. Have most these parts already and engine is...
