Jonny tig VS 6Boost exhaust manifold

[Hezabot]

Anyone used both Jonny tig and 6Boost and can give a comparison? I’m looking at getting a high mount manifold with a 60mm wastegate. Was initially looking at 6 boost but had a look at Jonny tig set up today and also told by that particular tuner he prefers JT. Can anyone comment, if you’ve got just a JT and have something to say please do. Pros and cons of both would be good

Cant answer your question.

But I did try to buy a 6boost manifold once. The guy (Joel?) asked what I was going to use it for - I told him.... basically said I was an idiot and the conversation ended.

He was right - I didn't need a new exhaust manifold for my application - probably right about the idiot part too...

Here's a pro: JT is just up the road from you so if you wanted to modify the manifold at any time it would just be a short drive and short turn around with a bit of organisation.

Good advice

Yea I noticed. Already seen him and decided to go with his manifold. I’m looking at cracking the 600rwkw mark now and at some point down the track 800+

Are you going to use the same turbo to do that or two different ones? What is it/are they?

[Hezabot]

Two different turbos, using a gtx3582r gen 2 for now (bought it brand new and only done 2000kms so want to get a bit more use out of it). Gonna change the housing to vband then latter on the hole can just be enlarged for other turbo (so I’ve been told). Wanna get used to the power before going an insane amount, not saying 600 isn’t (if I get that out of the turbo, some seem to think 550 will be about max but some say it could do 600

[Puffwagon]

Is that with a stock ex manifold and rear housing for the gtx?

 

Any chance you can log the ex manifold pressure vs intake pressure? 

 

I have the same turbo with similar km's and plan to wring it's neck shortly as well. I'm not sure that I'll log the pressure differences but I am curious to see when the hot side starts to run out. 

[Hezabot]

It is on the car right now with the standard fg manifold and rear housing with the internal gate. When I get it re tuned (new engine going on in a couple weeks), it will have the Johnny tig manifold with a 50mm external gate, housing will be changed to v-band with no internal gate at all.

 

Explain what you mean by getting those pressures? My boost gauge is direct off the plenum, but I have no sensors for exhaust gas pressure.

[Puffwagon]

You want about a 1:1 ratio between those pressures.

 

If the hot side starts getting much higher then you need to look at a larger turbine housing a/r, larger turbine wheel or larger wastegate.

 

From what I've gathered the stock rear setup, even with a ported wg, would be a bit restrictive when pushing the 66mm compressor to it's limit.

 

It'd be nice to see a log of this.
