**update**

placed order on at power bodies and filter, 3.5reg, 708 cams and placed a deposit on a predator for the end of the month.

I can see your determined to get 143 like me LOL

sexy_gt · 15th January 2011, 18:47

anything above yeah id be happy

adzvtr · 16th January 2011, 02:48

mine made 147bhp and 125ftib torque on 708s with andys map on the predator.
and mine was quicker than one on same spec cam making 155bhp at chipwizards on standard ecu.
the proof is in how the car drives m8. if ur happy dont worry bout the figures

i just want to hear these bodies sing

I'm from Grimsby, yet I didn't know we had a set of rollers here lol

sexy_gt · 16th January 2011, 16:06

we had one at RASP.
they are currently re-locating to a new premesis, so no rollers running at the minute.

Hi all, very interesting posts! I had my 16v dyno'ed! It was very loud that's for sure!
TB's sang lots! The guy of the RR said his rollers gives bhp at the wheel and torque in FtLb. After two hours of mapping (the omex ecu which we found to be very user friendly), results were: 159bhp at the wheel and 135 ftlb torque. It is important to have the bhp tested on a gear that is 1:1 in my case it was 4th gear (before i had the quaife box fitted). I guess its about 190bhp at the flywheel!

AndySAXO^p · 16th January 2011, 20:31

Hmm what spec is the engine?

AndySAXO^p · 16th January 2011, 20:32

On Saxo 4th gear is the closest to 1:1 not a 100 % match though.

Tyanu888 · 16th January 2011, 20:57

Spec:
PT52's Kent cams, high comp pistons (Wossner), carillo con rods, stage 3 cylinder head Gas flowed/ported, Omex ecu stand alone, Webber injectors, jenvey 45' TB's, 4-2-1 exhaust straight through 2 inch with powerflo back box and i use high octane racing fuel (VP) 109RON. I use the car for hill climbing only!

O sound good but 190 ish bhp on Kent pt52 camshafts seem a high, if I ent mistaken they are close to the spec of 708/ph3 camshafts and them with high comp throttle bodies will be around the 160 mark at the fly not at the wheels

That sort of power more ph4 cams unless I got my Kent cams wrong, but would say that dyno was cala the figures back at the flywheel with a figure like 160 ish.

Tyanu888 · 16th January 2011, 21:29

surely not! I was assured it was very accurate and at the wheel not the FWheel. The chap had his rr imported from Australia and he definitely knows what to do, he actually went to Australia to learn, he is the best one in Malta. My cams have a duration of 278 deg. I think a lot of gain came from the high compression besides the good mapping. Well it works amazing, its great fun! I only use it in hill climbs though, it would cause a lot of trouble in the road

Tyanu888 · 16th January 2011, 21:31

just a sec, 159bhp at the wheel not 190ish! just to be sure! The curve in fact is fantastic! Oh by the way it revs to 8300rpm!

AndySAXO^p · 16th January 2011, 21:41

Hmm yer think I got mistaken the or 52 are close to ph4 cams, and hope your on solid lifters then with that rev limit, hyrdo followers will break down at that sort of rpm.

And you did say it was 159 bhp at the wheels which is 190 ish at the flywheel, I was just going of what you said.

lol wasnt sure, imagine 190 at the wheels.....mmm! lol!
Yes i have solid cam followers! Done a whole season last year and worked fine! It was testing year, now this year is winning year!

back to Sexy_GT's query, i think you lost bhp because of the high mileage, probably new rings will give you a much better result. What do you think Andy?

AndySAXO^p · 16th January 2011, 22:00

Yer I was not sure thought pt52 where different camshafts, and yer going to say soild lifter would be needed fit that sort of rpm, and I am unsure I think yer was just wear on an old engine losing some power,

Yer re ringing pistons could help but might not be worth on just a track toy, unless it totally goes I guess it depends on money and what you want,

I got high comp pistons on my engine because I knew my old engine wasn't too great was starting to go.

adzvtr · 17th January 2011, 23:03

doing a compression test should show any signs of rings starting to fail
