so whats a good lobe sep for decent sized power band... 115?

wanna make good torque from 2000-3800, without sacrificing too much horsepower.

cms stage 3 looks good, but says headwork is needed first?? cant imagine it wouldnt run on a stock head...

you can't just look at one part of the cam.

a hint when picking cam. choose a realistic power band. get on all the cam web sites you can and copy all the cam specs they have that suit that power band onto word doc.

then compair all the cams. it will soon become pretty clear what cam will suit you

yeah thats what i did,, there's a sticky Doc already done up here, i added surecams cams onto this and away you go comparing. easy

In my veiw the camtech cam stage 2 cam is the way to go according to your engine & car specs.
You need somthing with very strong mid range power due to the nature of the ford 6i engine.
It's not made to suit high revs. The stroke to rod ratio is like a stroker, all made to work low to mid range. That's why the ecu has a rev limiter to 5750rpm. I am a little bit consernded about the std. ecu. If you can get a xr ecu & xr fuel pressure regulator it will be better. With this cam you will need springs. Yes the xr valve springs can handle 600" lift (coil bind) but has it got good seat & open valve spring pressures. The right valve spring is determand on the cams ramp rate on the lobe.
I also would give the head bigger valves inlet & exhaust & will give the head a low to mild port job.
AU head gasket to raise the comp. Don't go to big on the ports. The bigger the ports the more up high you have to rev the engine to work.
This is what i would do in your shoes.
I hope this helps you in some way & good luck with it all.

Well with big cams in my experience, with good gearing....i had 4.11's. soon to be manual with the 3.45s

i was running a .554 lift cam on intake and exhaust 220@ 50 duration with a lobe separation of 111.5, (matched to the head 365HP flow at .550) its a high revving cam, but with the 4.11s and auto it PULLED! very well right off the line which was with a stock 2200 stall... any taller i feel would have been bagging wheels off the line.. and pulled strong all the way to the limiter 5700, but felt exceptional above 3000..., i loved this setup, just enough (lag?) bout half a second and your into the cam range not to be spinning all the way up the street....

saying that , thats probably beyond the stock ecu....., i ran about 20L per 100, it IDLED!!! like a v8 dragster which is NICE, braking was slightly effected.. needed a little more pedal effort. BUT general driving it behaved well, didnt miss or do anything funny like that, no flat spots.... so the standard ECU copped it "well" i think if you can handle doing 20L per 100, but again above 4000 it was LEAN.... i did a few skids, just holding 4500 so i wasnt flogging it too hard, and the extractors all the way to the cat were glowing... so yeah down the track not good for the valves etc...saying that below 2000... RICH obviously 20L per 100 so probably protected the valves for lean running flogging ( ALSO took about 2 weeks for the computer to settle with this cam. IE.... Stalling, flat spots, missing, MORE fuel chewing.. but did learn a relatively handleable tune, i took that cam out till i get an AU computer for flash tune ability.

Overall it was ENJOYABLE!!!, but stupid with the fuel bill, not good for the engine, and i think it was a LOW 14 car 14.2? considering i would flog my old friends stroker v8 which ran 14.6 and my tuning was f**k lol

Im curious to see what i run with a manual and a TUNE. i'll be dissappoined if it not running mid 13s

Duration at 50 thou is 215 intake and 215 exhaust with 265 lift at the cam and 110 lobe seperation.

can anyone give me some info on this cam? camtech recommended it to me

Fitted the 1543b profile from Wade and its fairly lumpy. I think it might be leaning out, did a quick check with the multimeter on the o2 sensor so might get it on the dyno in the near future

Going from a cam with 110 lobe sep to this cam with 114 degrees you can notice a big difference the way it delivers the power. It feels more tame because the power range is fairly broad, but still needs to be high up in the revs.

cold start idle.......

what happens when you run a bigger cam with the ISC blocked off

[youtube]http://www.youtube.com/watch?v=v8NDxicUzGw[/youtube]

my cam only "hunted" like that for a little while to the ecu learnt it. yours will prob be the same... my ISC was also not connected lol

ditto
and hasn't hunted since (over 6 months now)

cant go past CMS cams.

dont have the specs for you, but they are the only ones who do well at ALL of the drag and dyno days i have ever been to. 1st, 2nd and 3rd prize every time.

i am running a CMS stage 3, for a 14.4 @ 96mph, and averages around 155 rwkw and 375 nm at 5000rpm

my other mods are intake, extractors, exhaust, mild head work. still running standard ecu and standard bottom end.

Been a few days now and cold starts are really f**k. Its not even hunting as such, but more half-stalling then revs to save it from dying.

Also have a nice pile of black soot behind where i park the car, idle is very rich, but at peak revs it seems to be lean with the o2 sensor showing 0.10 to 0.30 volts.

Looking at getting fuel/air ratios looked at, then will see if i need larger fuel regulator, then will get a tune done.

Very happy with the performance, just the cold starts are really annoying. Fuel usage is 8 litres/100km on the highway, but around town is shocking. Once i get the tune done and LSD fitted im looking forward to some decent numbers on the track..... hopefully

Thats a very good time, i'd be happy with that. Would be interesting to find out specs on his cams as they sound good.
