AT performance Throttle bodies vs Jenvys

[Wodja]

Has anyone had any experience with AT performance, i am looking at going from 40 DCOE webers to throttle bodies and this company AT Performance seem to be at a quite reasonable price.

How do they compare to Jenvys?

I will probably be looking at using an Omex ECU, instead of there Typhoon system but apart from that they look really good!

Any information would be great.

I am planning on using these once my RV8 engine build is completed and run in on the triple throttle bodies I have at the moment. I'm sold on the idea of them but I'd still be interested in any comments from anyone who has used them.

Mate of mine did back to back runs on the dyno recently with a variety of bodeis, AT's outperformed Jenvey DTH bodies...and on this particular engine, Jenvey DCOE's outperformed the lot - which he thought might be down to how the manifold followed the curve of the inlet port.

Ideally what you need to do is find someone who builds your particular engine and see what results they've had on the dyno.

Using AT's on my MGC very pleased with engineering and performance, the Typhoon ECU has all that one needs , the software is a bit bland but functional.

AT out flow the jenvey for the same size of body, apart from that there's not a lot in it. Be sure to specify the type of quadrant and throttle cable stop you want -I recommend using the tall version so it clears injector wiring, also consider the distance you have between manifold, air box depth, this will determine where the air box plate will sit and that dimension need to be big enough to clear the injector rail. On RWD or front mounted transverse engine this space is not so critical compared to firewall side inlet.
