It just means that neither the inlet or exhaust were a restriction to power at the boost i was testing at(15Psi). I still havent tried the quads. I`d be suprised if they make any more power. it is the throttle responce that should improve.

I did test as high as 25Psi yesterday without hurting the engine. But i wouldnt like to risk it over a race distance.

I havnt taken any photos or video of the engine for a while.

Just a manifold shot would be awesome, I never thought that inlet mani was a restriction just not responsive like u say but you where making do with something that was made for LPG first so you did awesome with what you had.
Although often overlooked before the A12 will never be again after your efforts and we hope you continue to enjoy your creation with some records on your way :)

I`ll get a photo up. It made 185Kw At 25psi.
Im looking forward to getting the next engine finished so i can lean on it a bit harder. The 36mm turbo restrictor will limit it to about 220Kw.

Excuse my ignorance but is that 185rwkw?

yes, at the wheels.

Man that is insane!!!! Well done! I have a 3tgte (1.8l twin cam 8 valve) in a ke55 corolla which on 25psi made 234rwkw and that's a weopon to drive but I have a lot more capacity than you so well done once again that's incredible.

Totally forgot about restrictor! is that why previous long runner lpg inlet mani did well?

1179cc A series + Simon + 34mm restrictor = 185kw @ wheels ...Holy Moly!

TimTams, imagine no restrictor plate KWs! :))

Thats a lovely looking thing!

What are the rules around the restrictor? I assume before turbo, but anything around transitions? Optimising the contraction and expansion either side will make a decent difference. I'd reckon you're on top of that though, just couldn't see it in the pics.

Again, nice work. I'd like to chat about your trouble with the injector placement sometime, as you know mine will be mounted outboard.
