surely a 4.5 is 395 bhp at the wheels, about 450 at the flyGod knows why but the two RR are consistant but clearly work in different ways.
Indeed - this thread shows it - the maps on Getsis car was one day apart.

My personal opinion is that the lower number is the more realistic one, it just seems more logical to me.

actual performance figures will tell you who has built the strongest motor?
Who cares apart from willy waving in the pub? I'm more attracted to the improved reliability of a head that doesn't have finger-followers and that has extra oil and coolant pathways. Something that has been engineered to address the flaws in the engine rather than just making bigger numbers on a dyno.
I tend to agree, When I had to get my SP6 rebuilt reliability was my number one concern, I believe I have that now with my TVR Power build. However it is comforting for those who have spent money upgrading the performance to see that there car is making more BHP / Torque if that is what they desired from there build along with the reliability of course.
when my T350 died it already had valve guide wear but the liner on number 6 cylinder slipped and caused the breakdown, so its as much built quality as parts failures as far is I've been concerned. The tvr power re-build was solid though after and as far as I know 5 years later and it's only needed a water pump changed.

No not willy waving at the pub, but the track.I'm more attracted to the improved reliability of a head that doesn't have finger-followers and that has extra oil and coolant pathways.

I am simply saying to the Dyno racers, do some actual performance figures to see which build performs best, not whose bit of paper has the highest point.
what amazes me is that when you go back to the drag race table Cyclone's 11.9 quarter is still the best non assisted AJP cerbie on there (or was last time i looked). Has nothing moved on in AJP circles since then? There's some high hp cars out there but none has gone faster than 11.9 yet with a non assisted ajp8. At this rate the SP6 boys will be whipping the AJP boys!
I wish Mike Saunders would take his lightweight 4.7 down the strip to see just how fast that would go!! The AJP boys need a bit of a lift.
Even me with my AJP bias is hoping to break 390hp with my latest mods on the tiny 3.6 Sp6. And I never thought I'd be excited about SP6 tuning, but it's addictive when those numbers keep going up.
Whatever your engine of choice is, times are good though

That's for sure. Paying £20k+ for an engine which detonates almost instantly was a darker period than the crappy factory rebuilds. The most important thing is the competitive choice and the reliability otherwise there would be no S6 Tivs in a few years time.

I guess the real problem the AJP has is that there just aren't enough units out there to enable a developer to amortise the investment quickly enough?I wish Mike Saunders would take his lightweight 4.7 down the strip to see just how fast that would go!! The AJP boys need a bit of a lift.

Good point. The S6 has been used in the Cerb, Tamora, Tuscan, T350, Sagaris, and exotics & prototypes. As you say, a lot of units out there. Gassing Station | Speed Six Engine | Top of Page | What's New | My Stuff
