Hey EVOm

So here are my current peformance mods.

RRM UDP
RRM CAI
RPW Header/Downpipe
Full 2.25" CBE w/ High Flow Cat and 2.25" Muffler
Tuned Haltech Interceptor ECU

Next mods:

1. Twin throttle body
2. Intake Manifold
3. Camshaft and Cam Gears

My question is, which of the three next mods would give me absolutely more torque. I just want more torque (with the car being N/A) - thats my focus.

Cheers!

 

the twin Throttle body is not available and in all honesty would be a waste of time on this size engine - you need a 65mm t.b when you get the t.b you then just need to port match the stock intake to match the same opening profile of the new T.B - while you ar getting that port matched then get the intake runners ported as well this is more of a smoothing outand removing any left over castings from when they were made.


The cam shaft will give you more top end power than torque but you will see an improvement when you add the throttle body no point having all that extra air coming into the engine if it can't be used...

I think you should look at the throttle body and intake manifold as these have to be done together anyway you will see some improvements then get the cam shaft have it all tuned up and see some very nice gains

 

Twin TB is not something that can be done easily on the ralliart models sorry. The big single 65mm TB option is the next step with a redesigned intake manifold (Our performer series) and tuning.

Meanwhile I would focus on some other things like - suspension and handling.

 

RPW lists it under their available RA mods. Which i thought was weird b/c when i talked to dave we were discussing the 65mm TB which isnt listed.

 

LSD... maybe to get that torque to the ground/wheels
maybe change to SRI, i think they give a bit more than cai from what i have read...

 

ya sri intake will give u low end tq, and CAI will give u hi end hp

 

I did not see the 65mm TB on their website. I would like to see proof that this is actually worth something.

 

they dont list it and as far as i know still havent sold one. i had to email them to get any info, costs about 450 AUD.

After doing research and talks with a bunch of ppl not worth it at all.
