^ I'll have two comparisons by the end of this week
Look forward to seeings frak's selection!!
awesome thread revival!! never would have known it was there otherwise.
frak; what are the chances you have some dyno graphs of some 7age engines with different cam setups?
Sorry guys haven't done a 7age, I was flat out at work today, so haven't had time to do scans, have day off this week will do then.
If anyone wants to donate a 4age big/small port head in good condition I can get a 7age together with bits I have at work and put on the engine dyno, of course then a selection of cams would be nice to do some back to backs.
Great thread and an awesome job done by Frak and the boys.
Sure lots of people will benifit from your discussions and the information your guys have supplied.
Im intrested to see the flow bench results of the 16V Big/small port heads. Also the results of the dyno's back to back with the combo's on the 7age, Big port head especially.
Great work Frak, keep us up to date with your findings.
so has anyone else got any printouts or any info on their experience with 7age and aftermarket cams??
bump. anyone got more results?
This was my setup, made 82rwkw at uni group. I never kept the dyno printout, but it had a flatspot around 4500rpm and gained around 25kw between 5000-5500rpm before being pretty linear to max power at 7500rpm.
4age smallport
4-2-1 extractors
292 degree, 7.5mm lift cams
ae101 itbs
130mm trumpets
adjustable cam gears, cam timing same as stock
292s would make max power later than 7500 i would've thought? is that stock ecu
this is nuts. i have 80rwkw at 6900.
4age 20v bottom, bigport head. 40 Webbers.
standard everything except .8mm TRD gasket
i think you needed to dial them in just a tad!
on a personal note: anyone happened to check valve/piston clearance with 20v pistons and bigport head? (hahaha)
I think im just gonna buy some 264/270 8.1's and see what happens...
Mine has max power at 6000 :?
