Sounds like some basics aren't right so makes you wonder what else could be suspect. Last thing you want us a broken motor.I think most people find about 13ish psi is about right for 300ish on the FG factory turbo.You shouldn't need an eboost - there's no reason the factory boost control can't be tuned correctly for what you want to do. 2 Link to comment Share on other sites More sharing options...

Noob alert haha.

Yeah mate, goes to 20 PSI. Glad I was not the only one that thought that. When they showed me the dyno results, I was like, "How did you get so high in boost but so little in power?" I honestly thought I'd get more. I thought the stock turbo would hold up until at least 400kw? Link to comment Share on other sites More sharing options...

The BA-BF and FG F6 turbocharger is bigger and can support approx 400 on 98, but that's out of it's efficiency range (same with the figures quoted above for the smaller turbo) and a bit more on E85. You also don't need to replace anything for the boost control until you get way beyond your current goals 2 Link to comment Share on other sites More sharing options...

So if you are paying for a tune you shouldn't need to spend anything on boost control hardware.Factory FG turbo tops out around 320kw. It is a good, responsive turbo on the Barra though, so if you shoot for more power and go bigger you will trade off a bit of response on the street so depends what you want to use the car for.Edit: posted same time as Keith but same same. I should have said I was talking 98 not E85 1 Link to comment Share on other sites More sharing options...

Still learning what the Barra can and can't handle. So having the Pulsar 3584 is too big or it'll do just fine? Link to comment Share on other sites More sharing options...

Frank Castle 85 Member 57 Member For: 4y 15d Posted 07/02/21 09:51 AM Author Share Posted 07/02/21 09:51 AM Yeah it is, I got it for cost price. I've been told and I don't know how true it is, is that they're the rejected Garret ones. But, people seem to be doing just fine with them. If it dies on me, then I'll get the proper Garret one. Have you used BarraMods website for buying parts? I keep seeing that page smashed over the Barra pages on FB and I'm all for supporting Aussie companies, would you recommend?

BJSXR6TMKII Member 30 Member For: 4y 7m 25d Posted 11/08/21 01:47 AM Share Posted 11/08/21 01:47 AM With the HD Timing chain kits, empire elite have 3 options, street, elite pro and elite, would the street kit be sufficient enough for around 400-450rwkw? Is the elite pro and elite just for massive power? Link to comment Share on other sites More sharing options...
