The V8 Owners Forum -

Probably one of the most popular swaps engines about.

Interestingly... Whilst binnin 20+ years of shite, found some paperwork from the RV8 stuff and the DW270 Typhoon cam. Although it's probably readily available anyway Intake Lobe centre 110deg ATDC Lobe centre separation 110 camshaft degrees Duration at 0.050" lift is 221 intake, 215 exhaust Cam...

My Discovery 1 V8 on carburettors failed its MOT on emissions, carbon monoxide level 3.71 versus Max limit of 3.50 failed it. Same thing happened last year I was lucky that time as there was a guy available to tweak the carbs. I have been looking at the Gunson gastester which according to the infor...

LOL, just seen one of the video's, it'll be wellll into Sports Libre anyway. Hell of a project !! Sort of a part spaceframe type project, exoskel etc etc The V8's are very cheap I believe, and of course turbo would be great. Although if staying near standard engine, maybe one of the Audi V6 supercha...

Always annoying that stuff like that will get forced into Sports Libre, which has lots of rules and ££ stuff needed.

Are you going for a transverse layout or longitudinal ?

I guess if Audi, must be a longitudinal and fwd type in line box ? Porsche PDK would be nice

I would say a cam swap makes the most sense.

So the question I have to answer now is do I live with this as-is or pop a new one in there? Not a job I particularly want to do (or pay for) but could make the car a whole lot more satisfying to drive. It's horrible having to do work... The experiment I tried with the turbo Mini and the Kent 286 w...

That's what I would have expected. Theoretically, a larger valve overlap should only make sense on a turbocharged direct-injection engine. It would improve scavenging without heating the exhaust. Interesting! I'd never thought about that before (due to my problem). :lol: Cheers No. Overlap can only...

Obviously theory and reality....can be blurred. It would take special equipment to measure valve lift in real time to see what the Rhoads lifters actually do, and when they do it, as I'm sure even oil types and temperature will playa big role in that too. As for turbo requirements, depends on the ov...

Well I wouldn't say the behaviour is crap, probably more like sub-optimal. Anything less than about 1200RPM does not pull smoothly, I know that sounds like very low RPM but it would work very well in my car when at slower speeds which are a fact of life. I also think this is possibly why (or at lea...

As is often the case, more isn't always better. Sacrificing a few horsepower for better drivability is often a wise decision. Regards A great quote in DV's A-series book I think it was, and perhaps others regarding camshafts. Pick the camshaft you want, then buy the next stage/level down from it.

One other thing I did wonder about is whether there is any lost motion with a hydraulic lifter. I've never had one of these apart but I'm guessing they have some sort of port in them to let oil in which will close off as the lifter rises (similar to a brake/clutch master cylinder) this could result...

A quick google for some cams, Given some numbers here are quite high, I would think they are trying to quote seat to seat. http://www.wolfitt.com/kentcamdata.htm A chart of different cams, again it doesn't specify https://sideways-technologies.co.uk/forums/index.php?/topic/7653-cam-comparison-chart/...

It is common for durations etc to be quoted on a 50 thou basis, or 1mm ( not the same oddly ), so that can vary by cam manufacturer. Generally they don't go by from actual lift from zero to actual close....but sometimes that can be given too. I presume some of that is because all cams will have a so...
