-7/9s Or -5s Garretts

Think I am running low 20s at 4k. Don't quote me on it though.

Not likely mate Piggaz 2.8L stroker with all the fruit is probably at around 20psi @ 4K. Full boost on your car would be around 5-5.5K id say.

I'd hope not - my GTRS's were on full song @ 5.5krpm.

When I had -5s, the turbos were getting tickled at about 3.5krpm and pretty were in 'get up and boogy mode'.

Both examples on 2.6ltr.

Sounds about right.

That thing of Paul's is a weapon, and not the average build. It's got ALOT of rnd and tricks, all of which work. A lot of secret squirrel.

yep totally agree with you.

IMO -5s on stock 2.6 will see full boost around 4.5-5K - if you get it earlier than then I want to know.

[XGTRX]

So your saying if I am running 25lb then I am not making 20 at 4k?

[Ants]

firstly are you really running 25lb????

secondly if you are, how bout you throw a dyno chart with boost / rpm curve so we can see at what RPM your really making at full boost with -5s....then we will all know.

I'd really like to see an overlay of -9s with -5s on a dyno graph.

Does anyone have this info or happy to post their graphs running -9s and another with -5s...from here, we can overlay to see the difference...would put a lot of debate to rest

[Ants]

+1

There is one out at unigroup on the same car. On the dyno, they came on exactly the same but the 5'a made more grunt. However, to drive they were a TOTALLY different car!

[Piggaz]

What's wrong with running 25 psi Ants?

LOL....I was wondering when you were gonna say somethin.......aside from being a ship load of boost nothin really just curious.....about how long an engine would last if predominately driven at that boost level

That is odd Paul. Dyno shows that they huy full boost at same rpm?

Didn't answer the question.. why the doubt? I am offended.

[Marko R1]

'Hit' not huy lol (wtf is that word)

[Piggaz]

Ill try and get the sheet. Or it could have been the power low end was the same but boost levels were pushed to the right a tad on the 5's.

Leave it with me.

I spose the tune would have a massive part in this. Mine lasted 7 years with anything upto 2.0 bar shoved down it... Only died because the oil pump had a hissy fit.

[Mick_o]

yep totally agree with you.

Mate I watched a built 26 with -5's and poncams on a dyno for a good hour and full boost was by 5000 and it went to 345kw iirc. No chance of getting -5's in by 4 on a 2.6L

IMO -5s on stock 2.6 will see full boost around 4.5-5K - if you get it earlier than then I want to know.

[Ants]

I know Paul.....I know. I'm just conservative and want to have an engine tuned to last as well (I will certainly not push my advance spec beyond 25psi). Your car is insane and would of loved to have a 2.8ltr with similar mods to yours

Keen to see those graphs though.
