This has been passed on to me, thanks. In the absence of published figures this is all we have to run with;



So, comparing the Wade 104 to this, yes of course the RE13 will generally outperform it, however they are hardly the same profile, not even close. They are intended for different purposes.

Hi Austin 850
Please don't listen to any one on here on how to set the RE83 cam up as you will only go backwards, i designed and tested it and thats where it works best and you will loose top end performance if you retard it.
GT MOWOG why would you put a 140 wade cam in a in a daily driver? to start with that cam will make peak torque at 5500rpm (295 duration)i don,t run that much duration in my race car, and will make peak power at 7500 rpm .
One reason i don't give out timing figures is because it realy does confuse people when trying to get the same timing figures on each valve with the mini rockers,GO READ MY ARTICLE SMALL BORE PROJECT and you will see what i mean, setting up the cam using the full lift figure is more accurate,
Your wade 104 cam is a very lazy cam for that duration 270 and 212 @ .050, a std mk 1 cooper s cam with with 240 dur has 212 @ .050.
My RE 83 cam ( just to keep you and your friends happy)has these figures
duration 260
Valve timing IN OP 20 deg btdc closes 60 deg abdc
EX op 60 deg bbdc closes 20 deg atdc
Cam Lift .270
Lift @tdc .o83 in and ex
DURATION @ .050 234
But that tells you very little about this cam
And just for the record the RE13 with .020 tappet settings has 268 duration and 236 @ .050 lift

OK, thanks GR, what's the LSA on the RE83?

Don't worry. I've no intention of pulling my engine out to do anything to it at the moment. I've only just got it on the road again after a long break.

Is it likely that 1.5 rockers would give me a bit more top end?

Cheers,
Simon

I was wondering what is the key difference (where is it designed to preform) between the RE13 and RE83

I am running a RE13 in my 1360 and its certinally performs well. My engine was professional built which certianly helps.

HI Austin 850
Don,t put 1.5 rockers with that cam, it was designed to run with 1.3 a true 1.3 as in roller tip 1.3. 1.5 will not make any more torque or hp as the cam is only a 6000rpm cam will run to 6500 but going down hill, but can be made to make a lot of hp with the right bits by 6000rpm,
where as the RE13 with the right bits will run to 7500rpm.
The RE83 is much more drivable and makes more torque down low but will pull very strong through to 6000 the only draw back with this cam is the noisy tappets i should have made the opening ramp a lot longer may be .026 instead of .015.

Thanks. I found it and have read it.

I see near the end of the article that there is a torque / power table for various combinations, however I also note that the figures are un-corrected so don't directly compare.

Hi GT MOWOG
All the testing was done on the same day and as far as i can remember the figures were corrected.
BUT please do your self a favour and read the original story in the MINI EXPERIENCE craig watson has it as mini mania re wrote the story and changed a lot of it around and left a lot out.

Thanks Graham. I might get hold of a set of 1.3s then.

Hi GR,

I dug out issues 6, 7 & 8 of TME with the Project Engine in them. I didn't read any difference at all between the on-line article and that in the magazine, right down to the corrections from the editor (Watto) and the uncorrected dyno figues. Fair enough you say they were done on the same day, but condition during the day, particularly between about 9:00 AM and 4:00 PM change enough to dramatically vary dyno results (that is why we correct them), so, sorry but the results are not comparable with each other. It is the 'norm' to not only correct figures but also do A-B-A type tests to verify results and corrections.

ask a question and get a stupid load of replys, what ever cam you pick, its comes down to head work, exhaust set up , carby and manifold choice and timing. just sticking in a cam is not going to offer you much benifit unless you make a nice flowing combination of the rest of the engines set up.
GR hit the point that a big duartion is not always best, this is true for a low reving engine a large duration will loose HP so maybe u can have a small duration cam with a big lift
good luck with your engine .
