Agree there’s too many cams! With the bore/stroke/compression you’re running, cams with 250-255 duration @ .050 is a happy place and there’s just not much difference between them all. Bump to at least 12:1 compression or more and I believe you’d see more of a high rpm bump with a cam in the 265 duration @ .050 range. Would need to strap the 48s or 50s on there again of course.
Just stick with proven cam profiles over the years. And much comes to the whole combination of how an engine is set up by running good on a particular camshaft profile. You don't need 12:1 comp.ratio to see 180 Hp from a 2000 cc OHC pinto
Ive a Gts2 in my pinto. 10.5:1 CR engine builder said, big valve head, 45s on 36mm chokes, HPE 4 branch manifold. 156 bhp 135ftllbs. I was totally surprised as i thought id get around 170-175. Would i gain anything by going to any of these cams? Is CR to low? Need bigger chokes but ill loose low end torque. This is a fast road mk2 escort. Thks
I have seen over 180 bhp from a gts2 with a really good head 11.3 cr and 38mm chokes in 45’s. Bigger chokes shouldn’t hurt low down torque massively if you tend to feed power in, but if you just stab the throttle straight to wot then yes it will seem like you have lost a chunk of torque
you do get a feel for differences in how they drive on the dyno, but you cant put that in a graph! These cams are all so similar there will be very little difference in how they drive, unless you drove them all back to back i doubt you would even notice, with the possible exception of the GTS3, which tailed off faster at teh top end
Did you ever ( maybe i asked that question somtime before ) had a BLF 22 cam from Burton tested in a Kent OHV engine? I think its still a good one for the road use on twin 40 dcoe Maybe there is a Kent indepth tech. developement in future. Because these little engines do perform well.
ive never run that cam, might one day, trouble unlike a pinto where i once ran 9 different cams back to back, on an x/flow cam swaps are a pain in the butt
@@PenguinMotors well thats a surprise, because i am running one of them in my CVH and does perform well. How about change cores, what issues may i asked?
GTS 5 long oval? some say, but ya know the gearing is responsible of where your at... at most. I go for more torque at short oval, and a bit more high end at long oval, but they do not exist anymore. We had this wonderfull longtrack Oval nearby in Baarlo Holland wich has been closed 1998 for some bullshit environment but rather inevestment money reasons.
Great comparison. Im running a FR33 that would be great to see in action sometime. Cheers for all your videos
The cams are surprisingly similar, RL31 and WR40 have a very decent spread - thanks for the facts 👍🏻
No problem 👍

So not much has changed from the profiles back in the day? Thanks for another great video.
RL31 Has been a good cam to use in any rally car. If the car is not competitive, which now a days it won't be, the cam is not the problem
Surprisingly similar results.
Have you managed to do any test with the Kent RL30 camshaft? If so would it give similar gains to these camshafts?
Never tried it so don’t know but I can’t see it being dramatically different
Thank you, great vid as always.
Have you thought about testing crank scrapers?
That would be interesting, I'd like to see if a knife edged crank would make any difference too.
very interesting
so, if it is a road car, go for the one with the highest low down torque ? [40]
The number of available Pinto cams is TOO DAMN HIGH 😄
What are the valve sizes?

@@PenguinMotors might try bigger chokes 1st. Stick.with the cam for now. Thks
I guess the question then is wich cam drives the best. Dyno is one thing but actually driving is another.
you do get a feel for differences in how they drive on the dyno, but you cant put that in a graph!

What’s happening with the rover v8 with the bent rod?
Work in progress
Excellent can’t wait for the results , once had a 3door triumph Toledo with rover v8 awesome! Would love to do another.

@@PenguinMotors a pain in the butt, i have to think how that means in particular. sorry i am Dutch so give me time
Love the videos penguin!
What's your thoughts on Newman cams?
Newman is good, i say. But use them with their solid or hydraulic lifters. No mix match stuff i recon.
i used to use them, but stopped after they changed the cores and i had "issues"
@@PenguinMotors well thats a surprise, because i am running one of them in my CVH and does perform well. How about change cores, what issues may i asked?
Wish my engine could make this power😂
