Further A610 tuning questions

My a610 seams to be running 270bhp with 1.2 bar of boost and decat and exhaust system with nothing else, so I bet yours may be around 280 to 290.

Out of a 12v engine max 330/350 with a lot of head work and all the rest, the combustion chamber designe and spark location is crap, the prv 24v has central plug and better combustion chamber but the rocker and cam and oil supply design is crap. Can’t win but 400/500 with work and modern turbo / Ecu hopefully.

Dave Miles and myself both run effectively A610 engines in our GTAs, Daves car runs twin turbos and makes about 310 bhp at a bar, mine on a big single needed a couple of pounds more boost to make the same power, both with custom charge cooling , injectors, and aftermarket ECUs. Turbo will be most restrictive thing but I think you would make more than 270 bhp on EFis rolling road if you ran 1.3 bar or so , 280 ish I reckon. On the test day last year there were a couple of slightly tweaked A610s making 260bhp, yours should be capable of a bit more than that. What rollers is it going on some makes generally give higher outputs than others. Gearbox good for 350 ft/lbs if driven sympathetically. Internals good for at least that.

Thanks all! I'll report back on Friday evening. Not sure if the car will get on the rollers but I am taking the car to the tuning company for a check over. I'm hoping they'll say it's ok and start with the tuning!

It's a Dyno Dynamics dyno.

Good luck!!

Don't listen to Tony ...he says that about rollers when he don't like the outcome

Key is consistency....get a good tuner that you trust and keep going back.That way at least you'll know whether what you're doing is making it better or worse.BHP is just a number...but then so is weight...

It's how fast it goes that matters at the end of the day surely :0). It's not the outcome I don't like , just can't compare cars off different rollers as can be quite big percentage difference. If it's DD it should be broadly comparable to EFi's rollers. And you can have a inferior power to weight ratio and still be quicker if the power band is rubbish.

Its just like reviews in the magazines, they all report different speed figures.
Just get behind the wheel and enjoy it..... go to Macon.

Good luck!!

Seen seen ...I have the least of both but still second fastest ...I reckon if I'd not had that fry-up and/or taken a dump Ratty would have won the day at Brunt
+ You can also have a superior ptw and lose because you lunch yer gearbox every time you throttle it
When's the next one then? We were missing a few 'likely lads' there last time + looks like there will be more out to play so we all start Dellboy now then early Summer for a rematch??

Fighting talk let’s all go to the event and have a laugh, is the v8 allowed to the event my money will be on that to win.

...and his money will be in the ' shoulda installed a proper Porker box' fund


I'll just dial in a couple more pounds,fit the new ratios and take a shit

There isn't a fund for a proper porker 'box :0). I think the strengthened 'box will be fine as long as I don't got to silly launching it, the cam fitted moves the power up the band a bit so that initial torque won't be quite as brutal. Launching an aspirated car is less severe than a turbo car as you don't need to keep it on boost. I'm not expecting much better than the mid 4's 0-60 but from 20-100 it's going to decimate supercars :0). Will have a better torque to weight than a McClaren 540C.

+ You can also have a superior ptw and lose because you lunch yer gearbox every time you throttle it

Surely you can only lunch your gearbox the first time you throttle it? :0).

crack on then

I's just messin with ya Tone ...channelling my inner Angelols

You Southern boys don't arf take yerslves seriously....geezers et al ....
Just accept that that the Northern Powerhouse is where it's at ..South=mouth ...North=Worth ...nuff said seen seen

tony, whats the power and torque of this lump you have?
