As a American viewer that wants to build my own pinto for my Capri your videos are VERY helpful thanks Gram!
Very informative and well-founded. The result of the Bf63 surprised me a little. I would be very interested in a comparison between the KC camshafts GTS7 and HT1e. I will continue to follow it with great interest. Cross my fingers and wish you a good start to 2024, Graham.
Another really interesting back to back test, if I had to choose I'd go with the BF, even though down on power it would probably be a better all rounder.
thankyou for these excellent, no bullshit vids
young lads cam, + old codgers cam, unfortunately i would pick the bf63 these days...
keep it up my friend
As usual youre doing great work Graham. If only this around 10-20yrs agao when pintos and forum talk was at its most popular. Would've solved a lot of arguments back then and dispelled a lot of the bullshit. Great investment.
Spot on,what carnt speak carnt lie,love to see Graham try Kent RL1,I ran idf's 44 downdraughts,all whistle and bells,had good fun those days,tied by Rolling Road Auto Tune,RAT funny enough his name was Graham if my memory serves me correct.
Another great video Graham, thank you. Burnt fingers, did make me chuckle, sorry. So many decisions to make here and the end part was a great indicator of cam versus usage. Me personally, speed is not what I am after its the out of the corner torque where I'd be happy. Just need to pull my finger out and get on with the engine.
So good seeing what I used to run in my old escort
Pintos may not be like modern engines but they were simple good honest engines when BDA And BDG were out the Finacial budget , you can’t beat the sound of a set of 50 loyd webbers 😊
I salute your words "Draughts on full chat" carnt beat them,remember the rally's in Sutton park,all Super cars flew by (Quattro Lancia) every one started walk-in towards there cars,next minute Escorts,Manta's Vauxhall's,and others had "Draughts"belching,we would be running top speed to get our position back watch the action we could relate to our road cars,those were the days.
Good work. Both sound great. Yep, it depends.... Now that I am older, I would love to have this engine in a hot rod. Simple and strong. I do like Kents too.
Love the content,bringing back good memorys💯👍
Nice meeting you Sunday 3rd march 24'
likewise :)
Great comparison Graham, thanks
Great to see the visual graph you see the difference
Looks like the button although lower overall is lower, is the better choice. Who wants to being going past 5500rpm all tbe time for that extra gain.
I’d much sooner have the gains low down at Norma road use.
It’d be interesting to see a standard cam curve on there as well.
Interesting comparison.
Interesting as always. Cheers
Another great video! Would love to see Kent fr31 32 33 comparisons.
Great video 😊
More please !
My pinto engine in my Pinto had that Holley 390 CFM carb and manifold. I loved it. Very smooth with no bog. My first updated cam was too much for the street, Had to be over 3000 rpm to come off the clutch. Second one had a flatter curve.
BTW, my machinist had had success milling the head for compression so he took 0.1" off. I never had a problem with it. Manley also used to make a set of valves with a bigger Intake and a re-contoured Ext. I added a pointless ignition which improved the high end probably due to timing accuracy.
It was still pulling hard over 8000 RPM, but the gearing wasn't usable. I also found a 4.10:1 rear in the junk yard!
yes 0.1" off is common and about the limit to what you can remove
Great work mate, iv no interests in pintos one bit but your content is great to watch
Again another good test, only came to this channel for the Rover v8 yet still find the way you test the pinto pretty much with the average diy engine builder in mind very interesting. Thumbs up from me.
thanks, i do get commenst sometime that its pointless testing certain carb engine combinations because thats not what the professionals would use, but thats exactly why i do it, if mr DIY see a certain carb on an engine he will want to try it, not knowing that it may only work with a certain cam
@@PenguinMotors what a load of rubbish saying what you're sharing with us is pointless. With your back to back testing I'm sure you've helped a lot of DIY builders (and maybe professionals) make the right decision depending on their budget and exactly what they want from their engine.
Great Video!
Have tried from mild regrind stock to GP1 and the best all around cam I found with the pinto was a T3 Garrett turbo 😅 on a standard cam.
Nice
👍👍👍👍👍
I’d love to see a similar vid on the m10 engine.
Standard m10 with say a Weber 32/36 or 38/38 and a cam comparison.
Standard v Schrick 292 v 304
Greetings from Finland...I really like your tests for Pinto motors. Are these dyno tests, conserning of camshafts, made with totally stock cylinderhead or is the head ported? Forgive my bad english...
this hed is fully modified cnc machined
Very nice work, how am I only finding ur channel now ! Currently rebuilding an old rally 1500gt pre corssflow, any hints or tips for making a good fun fast road 1500 ? Not sure if it’s possible to take out to 1700 ? It’s fitted with bvh some sort of cam and twin 40s but was way down on compression so full rebuild is underway lol thanks
back in the day the magic capacity was 1650cc, the short stroke means 1700 isnt really on, unless you have a thickwall block or liners fitted. it will respond well to all the usual mods BVH, compression cam etc
..enjoyed.
What can you do for me and my 4.6 land rover...
Thanks for the good content! What do you think about the Burton BF134 torque cam?
i havnt yet tested one, but i do have one on order :)
Nice videos sir. Is this still 38mm OD ashley manifold?
yes
My second last pinto powerd escort rally car had a bf63 cam it was a 2.1 aswell, I loved the engine, good power and lots of torque, do you no what the compression was on the test engine, mine ran about 12.5 x1 . Great shoot out .
11.3:1
Would a pair of 48 Webers gain more power and torque or only power? What are the cons of 48s?
Thanks for your videos Graham.
i doubt you would see much of a torque increase, maybe a small one around peak torque but suffer a loss lower down
Can you do an elapsed time dyno run or time v‘s rpm graph to see how fast the engine is accelerating?
dyno accel rate is 200rpm per second
Swapped out a wr40 to a gts4 in mine, no good for my use. Had to go way down on idle jets, wonder why? Got drivability fairly good but lacks the punch of the wr40
It’s all depends on the rest of the engine specs but wr40 does have more low down power than gts4 but gts4 makes more top end power
Another good one Graham, will you ever test a Kent GTS1 cam in your engine, I would like to see the results.
Regards
Dave.
not yet but i wil one day
GTS2 as well. I've GTS2 in my pinto, would like to see tests done. Great content
Hi John, yes I would like to see the results also, if you can help me I have a brand new Burton BF63 cam that I did not use as I thought it may be a little wild for my requirements, it has only been placed in one of my Pinto heads just to check the springs for coil binding ( seat height ) and then removed. If you or any of your friends have a use for this cam please get in touch please.
Regards
Dave.
It makes the figures that they get from yank pushrod V8s seem even more impressive.
What are they claiming? I have no idea!
@@benjaminbenson8714 About 127 hp per litre
@@joejoejoejoejoejoe4391 that is bloody good going! Especially from a push rod. A very hot pinto over here is 200bhp. What are they getting on the other side of the pond?
@@benjaminbenson8714 Perhaps they "correct" horse power in a more generous way. Bare in mind it's from a single carb, with wedge combustion Chambers. I think they use a high rocker ratio, the valve lift is something like 0.9 inch. There seems to be a lot of secrecy surrounding the precise specifications. I think they have LONG valve timing.
@@joejoejoejoejoejoe4391 same here. Seems the more spent on the engine the more figure fudging goes on with the dyno!
I wish I was smart enough to have switched to a pinto in my mk1 knowing what I know now but…. Great video as usual Graham also for future thought considering everyone is using zetecs now how bout a zetec dynodog
i have a 2.0 blacktop.............................
@@PenguinMotors lovely should be great content to see that compared to a pinto same-ish horsepower for less $$$, I guess that’s why most people are going that route
Thanks very informative. What about these over 200bhp pinto truth or fiction.
most are fiction but not all
Looking for advice on EFI Pinto Cam
Will it run ok with 32/36 Carb Thanks for help Penguin
do you mean stock factory EFI cam? its the same as 2.0 carb cam
@@PenguinMotors Yes stock factory cam That’s good to know Will use it on carbs Thanks for the advice Great videos penguin
would be interesting to compare lobe acceleration rates, but the GTS cam has more intake open time, esp after BDC. I suppose I could look up specs of either cam, but what cam makers list is very deceptive. The BF cam is far better as a fast road cam. In fact unless you have a close ratio gearbox the GTS cam probably no better on a short circuit
most short circuit cars dont actually use the gearbox, once on the move they just scream around using only 2nd or 3rd gear
we would call that a grass track event, which are good value @@PenguinMotors
Compression ratio?
11.3
@@PenguinMotors thanks Graham👌
