What is the most HP I can get out of a worked a15 and what mods to the engine have to be done to achieve this??

depends on your budget.

flywheel hp 58hp is std - approx 150hp+ highly modified on a n/a engine.

just a guide line.

$15,000 AUD will get you 170 HP and the engine will last the duration of a 6 hour race.

For a engine that will last 25,000 km, $5000 will get 120 rwhp. Use a ported H89 head, dual valve springs, 272 cam, twin webers, 1.75" exhaust. And rev it up to 8500 RPM to make the most power as worked engines have less HP at low RPM than the stock engine.

i would except alot longer life out of both your recommendations. dd

I've been told I can get 225hp out of an a12 so how is it only 170hp on an a15?? Just curious

Quote:170 HP is not turbocharged. And if anyone says they have an A12 that makes 225HP naturally aspirated, ask to see the dyno chart. Talk is cheap.

225 go out of an a12 that Is pretty damn impressive. Not to mention how much that would cost....
At the end of the day within reason the sky's the limit a along as your pocket is nice and deep!!

is that 225hp out of a A12 n/a.mmmmmm ok & who "told" you that.

Ernie, what kind of HP can you build into an A15 that will last for 100,000 kms of typical street/highway use?

225hp is hard to get from an even a turbocharged A12. yes, ask for dyno sheet.
