What is the direction of rotation of the AJ30 engine? Just asking for a mate who has just rung and asked me.
Thanks

Isn’t yours a jag lump ? Mines a Ford.

There are two holes for the dowl. The jag must use one and the ford another.

I will get a photo.

Well mines up and running

Big thanks to Dave(40inches) for his help and knowledge on this engine on here and via email

Mapped yesterday by Dale @Bailey Performance and the results were awesome!

286bhp,254bhp at the wheels

https://youtu.be/cR57ENgqC_M

Wet roads on the drive home meant I didn't use more than half throttle, and it was still very fast

Brilliant Kev
What RPM was peak power at?
Doesn't seem worth the effort fitting ITB's!

I didn't take a pic of the graph,and Dale's printer wasn't working!

If Dale sees this he has it saved on the PC

Pretty sure the graph was still climbing at the 7100rpm limiter.

I did mention to Dale I had read of people running them to over 8000rpm,but he wasn't keen!!!!

The limiter was set at 7200rpm on mine and was still climbing

That’s a great result.

Any chance of some engine bay shots now the photo uploader is working ?

I would love to see what this engine could make with some long primary headers and throttle bodies. I just don't know how you would get them in a 7.

Dale's currently mapping a Lambo that was in the Fast and Furious 8 that is running a AJ30 in it now,that's got some long primary manifolds on it as it has plenty of space in the back of a Lambo!
It's also running cams and some high comp pistons,but still on the standard AJ30 inlet manifold.

The steering column is the biggest issue in a seven type car to make a decent manifold fit on drivers side.

Throttle bodies would require a massive bonnet bulge,or a big cut out with a massive filter sat outside the bonnet.

You have to re size them first.

I already have the exhaust manifolds but there going to be more suited to a Gt style car.

Rocketeer have ran jenveys and their own inlets on the dyno and the jenveys were down on power. I reckon I could fit itbs under my scoop but after seeing the results on a standard engine I'm not sure it's worth it. After seeing Dave's and kevs results on the st200 manifold I'm kind of a bit annoyed I didn't go that route. I always thought it just looked a bit restrictive obviously not!

Ive got a couple of st200 manifolds but mine needs the throttle body at the front as the rear is too close to my bulkhead in my focus, i did consider chopping one up and moving throttle body to other end.

The Rocketeer tbs where on very short inlets with sock filters that are well known to rob power.

I am surprised how the st200 mani performs. Given the restrictions here and the exhaust 300bhp can’t be far off.

I guess the question I really want to know is what it drives and handles like ?

You maybe interested in selling one?

If using the st200 setup do you need both upper and lower manifolds? Or do you mate the upper to the jag lower?

You mate the two together if i remember correctly. A member on here showed me how he had done his. Im gonna hang onto them just for now incase i need to cut more than one up to make it suit my application. There was one on eBay i think.

Ignore that last message, ive just had a look in my other unit and found another st200 inlet complete. So if you want one give me a shout. Its upper with throttle body, lower, injectors and fuel rail. Can post if need be.

I've used plastic AJ30 lower inlet manifold,then chopped up a ST220 alloy lower inlet manifold to make up the 15mm spacer required to fill the gap between the AJ30 lower inlet and the ST200 upper inlet.
Had to weld some tabs onto the sides of the spacer and drill and tap them for the ST200 upper mounting points.
