Id worry at results starting with 5..think about an engine soon then but if it starts then just get on with it...bit of premix in the fuel..

Yep
Pre mix quite heavily
I do have a spare in garage , only low 6’s
Hopefully never use it

Just bear in mind that if this motor has only done 2 time attack events after being freshly rebuilt then the compression will go up as the seals bed in

The readings are from my 8 engine , had to change the plugs so thought I’d try the the tester out .
Need to pull my finger out and choose a turbo set up for the REW ......
Pete has bought the turblown cast manifold and a turbo with internal wastegate .
So he’ll be limited to around 400 Hp which is adequate .
I’d be happy with that power ,  however , when I’m used to it I’d like the option to increase HP if I can especially having the Cosmo set up as a stand by . Looked at the turbo source ( turblown ) website about the internal wastegate turbo but  they say a Bridgeport engine is better suited to external  wastegate .
Manifold is the biggest hurdle , loads of Aussie guys run a single wastegate low down in the manifold with great success .
Before I get mine adapted need to find out best wastegate and best position for it to be within the manifold so I’m not restricting the manifold in any way . And not messing everything up ....
Need to try and do a lot more research but not getting a lot of time as I’m Very slow in work only using my left hand navigating a keyboard so work is piling up ..........

Ah right, doh.

He's using a cast manifold that fits the rew engine in an rx8?

As for waste gate placement, best place is in the flow path of the exhaust gasses

90 degrees to the exhaust flow it ok

Iv got a tial 60mm wastegate, you should be good with the same unless you just want to use 2 smaller ones

3 or 4 port boost solenoid is what your going to need though, control that boost regardless of what weight spring you have in the wastegate

Yep. Cast manifold from turblown
As for wastegate , I’ve read best to use two smalll ones but will struggle to get 2 pipes  returned back to the exhaust as there’s so little room
Basically need to get something like this
Turned into to something like this

Which shouldn’t be a problem so long as I know what pipe parts I need to get for the two into one adaptor for the waste gate and they are in the right position .
I shall keep my eyes peels for a boost solenoid
Thanks Grant

4 port boost solenoid is only about 40 quid I think, you will want to get some push lock fittings and line though to make it easier to install

If your wanting to make your own manifold then maybe stainless butt weld fittings as you can get all sorts bends and reducers, eccentric and concreic reducers etc OR get  the thinner wall stainless U bends like I used, although you maybe better reducing the pipe size to suit a T 4 flange however, depending on the turbo you choose it might have a v band entry.

Pick your turbo and work back from there?

The turbo source rx8 manifold with dual waste gates looks great but its a lot and requires custom thermostat discharge according to website I'm assuming that means to go ewp

Cheers
I certainly won’t be welding it , not a skill I hold
Having just read it I never knew they done one for RHD too
I guess I’m lucky I can adapt the one I have as a base point
Shame I could t borrow one from someone to copy and understand what fittings we need to plumb both piles into one waste gate .
So
Garrett G25-660
Is it best speak to them ask what I would get max output on a rotary ? If it’s only say 440 would I be better going for G25-770
Or going up to a G35 ?
