4-1 on mine for information, probably helps get the gasses out a bit quicker.

Mr Scuffs!!!! Where have you been hiding?? Nick, you have a 3" tullet dont you? What cat did they put in your system? Ive got them to get me a hsj cat from the states.

[NickB787]

I have a 2ublar setup and 2" primaries ( from the original thread) into a 4-1 collector (on over nearly 4 year now) with a 130mm cat Jim sourced for me.

[chris_uk]

Ah, my bad. Ive no idea what the specs of the tullet are.. Time will tell once its mapped if its any good. Lol

Mikes is not helped by being a miss-match port wise...

his is a 4-2-1 where they have paired 1&2 and 3&4, quite what they were thinking I don't understand... (if you're going down the 4-2-1 route, it's 1&4 and 2&3).

Also, looking at them, I don't think his primaries are 1.75", they look smaller than that (that said, I have not measured them).

Realistically, 3" is plenty big enough for 400+ hp, as with most things, it's the detail in the design and construction that are key.

All that said, it's making decent power and to be blunt, it's not lack of power that's holding Mike back (when he gets to the point that the logging shows 70%+ of the lap time on WOT, that's the time to chase more power)

Well said Simon, it is not lack of power that is holding me back, it is confidence and skill.

Saying that and to answer Nev's question; no amount of power is too much power until the power overwhelms the chassis.

Fair point Chris.

Did you get the PM from the hardtop guy?

[Mike (Cliffie)]

And here is the graph.

[siztenboots]

its the AFR thats important

[chris_uk]

I did mike, thanks again for that.

Did you get IAT and Duty cycle info from them aswell?

You would have to ask Ratty for that Chris.

[chris_uk]

Ill give jon an email.

Managed to grab an hour on the car over the weekend and started plumbing the NOS in.

Is that allowed this year?

It is in Club Pro.

Was it allowed in Club Pro last year?

What do you hope to gain with it, a boost to mid-range torque? If so how does the car compensate, or is the map already a little extra-rich and the boost of oxygen leans it off into the 'power' afr band?

I am very new to this concept so please excuse the dumbness of my question if it is so.

Whereabouts are you injecting it, Mike?

[fezzasus]

I think it's to cool the air, not for any specific gain.

[Mike (Cliffie)]

It is a wet kit so the extra fuel is injected as well as the Nos. It will help cool the intake temps but it is there for power hike on the longer straights. It is misted post filter pre-charger on the intake pipe.
