Trev Vaa 1,185 Posted May 28, 2015 Nice, I was thinking about going e85 how do you find it? i've run e85 in heaps of turbo cars, loves it, run it in a mates high comp LS motor, works well. just have to get used to the not so great economy. aka my big tank that's been made. you'd want 13:1 comp in your setup to get the full benefit of E85, but you are sticking with carby, so i probably wouldn't do it, the mixture isn't stable enough from the pump. hence why i'm going EFI with an ethanol sensor, can pull timing and add/reduce fuel as needed on the fly. servo list: http://www.unitedpetroleum.com.au/united/fuel/ethanol-85/e85-store-list Share this post Link to post Share on other sites
Olive Xm 34 Posted May 28, 2015 Not enough servos for me, I don't like the thought of getting caught out. Nice to know the one near my work has the "race fuel" thou. Share this post Link to post Share on other sites
Olive Xm 34 Posted June 13, 2015 Ok I have some flow figures... on a Superflow @28" LIFT INT EX TFC 100 65 48 66 200 140 93 144 300 210 134 210 400 270 170 268 450 292 186 276 500 296 195 280 550 296 201 284 600 304 204 288 650 304 204 292 Turns out the figures I had earlier were not off a Superflow, but something else and calculated. Im not sure on what to make of this. Share this post Link to post Share on other sites
gerg 10,871 Posted June 13, 2015 The bloke doing the flow testing should have some insight into exactly what's happened there. You should be able to hear a difference in the air flowing when flow drops that much and sharply so. Could it be a problem with his bench? Share this post Link to post Share on other sites
gerg 10,871 Posted June 13, 2015 Or maybe they were simply written down wrong for the last flow reading? (ie inlet and exhaust readings swapped?) Share this post Link to post Share on other sites
Olive Xm 34 Posted June 13, 2015 # edited results Im sure they are right, I just thought it would be closer to the Chi website results. Silly me. http://www.chiheads.com.au/shop/2v/2v-ford-cleveland/ I asked Chi and they said they have two types of chambers and of coarse I have the lesser flowing one, and they only get the internet results when they do the whole job...... Didn't tell me any of that when I dropped the heads off for the cnc. When I picked them up they said it would probably flow a little bit more. Kicking myself that I did not get them flowed before.

gerg 10,871 Posted June 13, 2015 Well that clears it up.... But those figures are nothing to sneeze at. Stock 2Vs won't even crack 200. Yours outflow stock heads before lift reaches 0.300", and have the potential to make 600 hp. Is that not enough? Share this post Link to post Share on other sites
Olive Xm 34 Posted June 13, 2015 Well it's enough to for now... Lol. I'm just worried I over did the cam, as when I was talking to cam tech they wanted to know flow figures and I quoted the web site. Share this post Link to post Share on other sites
gerg 10,871 Posted June 13, 2015 Well depends on your target hp and what you want to do with the engine.... Race only, street & strip or performance daily. With that cam it will be hairy below 2 grand and idle at 1200. If you can live with that then sweet, if not then it's too big. The flow improves little past 0.500 so what I'd suggest is a smaller one not so much in duration but in lift, if only to stress the valvetrain less. Your solid roller set-up can stay, just the stick can be toned down perhaps. Maybe see about getting it reground? I dunno maybe run it and see. Share this post Link to post Share on other sites
Olive Xm 34 Posted June 13, 2015 The old cam acted like that anyway so I'm not worried about the idle or the keep it above 2000-2500 factor. 2 Trev Vaa and gerg reacted to this Share this post Link to post Share on other sites
Trev Vaa 1,185 Posted June 15, 2015 it'll be fine.... so long as your fine with how big cam engines run (which you are) did you do a cranking compression test before you pulled the heads? you'll probably have a more compression in the chamber now, and you'll find the middle of the torque band will fatten up and be more driveable. this is the bit where you grit your teeth and hope the block will hold up and not split. are the figures you have quoted above the correct ones now? if so, should see 600hp, unless the heads become a choking point due to cross sectional area and port velocity.

Olive Xm 34 Posted June 15, 2015 Well the ones in post 103 are the most accurate that I have, if the flow bench was correct. Duggans use another type and they have to calculate it and they said flow was still increasing after 600" and flowed 340 cfm at 700". Im just hating that the car wont be ready this year to have a go at this thing. 1 Trev Vaa reacted to this Share this post Link to post Share on other sites
Olive Xm 34 Posted November 23, 2015 Hopefully a few are still watching this and I wont have to start a new thread. Ok earlier this year the engine ate the cam bearings due to what I believe to be low oil pressure, all others were ok and reused. so I sent it off and got them replaced and one piece rear main. Now I noticed that they did not reinstall the four cam bearing oil restrictors only the one lifter gallery restrictor, I rang them and they said they never use them as the cam pushes down on to the oil holes on the bearing restricting the oil anyway. Should I reinstall them? Facts, Engine is on a stand and the sump is still off....... I will be running the external oil line and have a High pressure spring in a standard oil pump {Ando76 go easy on me was only running the spring because of all the restrictors} I was not running the HP spring before. Low oil pressure was due to low oil level. Sucking in to intake via bottom of intake gaskets not sealing. Oil returns cleaned up and aligned Engine has grooved lifter bores. Now solid roller previously solid flat. Will be installing drain hoses into rocker covers Camtech Cam description Rough idle, strong mid range and top end. Modified engines only. Min 11:1 comp ratio, 4.1:1+ diff ratio. RPM RANGE 3200-7000 Share this post Link to post Share on other sites
gerg 10,871 Posted November 23, 2015 I thought the restrictor goes in the back of the block where the oil gallery plug is, and restricts everything above the main gallery. Never heard of individual restrictors in each cam feed hole. Share this post Link to post Share on other sites
Olive Xm 34 Posted November 23, 2015 Yeah one there and one in each of the last four cam bearing feeds. Pic only shows three thou. http://image.hotrod.com/f/37306696+w660+h495+cr1/hrdp-1205-351-cleveland-oil-restrictors-351c-oiling-fix-000.jpg 1 gerg reacted to this Share this post Link to post Share on other sites
ando76 4,354 Posted November 24, 2015 Nothing wrong with the HP spring in a STD. Volume pump in a Clevo mate. I think they give you like 80psi or so. I'm not 100 on the cam restrictors. I wouldn't use them. aren't they usually just down in the mains. Problem will be if they have taped the block out to install restrictors into the cam journals to fit the 'restrictors' as there could be a big hole left behind. admittedly the cam bearing only has a limited orifice size anyway but the big hole could cause pressure on the bearing in that area - especially with more oil pressure. Hard to diagnose of the internet but I would be interested to see any before shots - or installation shots of the cam bearing restrictors. It may not ever cause an issue as the pressure would be negated by the cam journal running in the bearing. This is where you need faith in your machine shop and their experience. 1 robbie reacted to this Share this post Link to post Share on other sites
Olive Xm 34 Posted November 24, 2015 You cannot really see too much of them once they are installed as they are in the main webs. This is not mine as I still have the bottom end together. http://www.google.com.au/imgres?imgurl=http://www.hax.se/rebuild-2002/restrictors-2-l.jpeg&imgrefurl=http://www.hax.se/rebuild-2002/&h=960&w=1280&tbnid=iI7uJyI4MW50_M:&docid=0JEAVQUZV-ODPM&hl=en-us&ei=hwJUVsbAFIau0gT9nbuoDw&tbm=isch&client=safari&ved=0ahUKEwiGoNactqjJAhUGl5QKHf3ODvUQMwgeKAMwAw Share this post Link to post Share on other sites
bear351c 10,270 Posted November 24, 2015 Have read around the 'net, that rodders in the US only run the one restrictor. No-one seems to have had issues. And you're running the extenal line anyhows...... Share this post Link to post Share on other sites
ando76 4,354 Posted November 24, 2015 Yeah looks like they just tap into the original hole. I'd have no problem running without them. Share this post Link to post Share on other sites
