Cam for Terracharger

[Commydoor]

Micky, i asked a while back about a 90mm throttle body. Im still going to get one but ive had a setback.
The charger and heads are off while i replace head gaskets. Cometic or ACL MLS type gaskets are fine? Ive searched through the posts but cant find any info on a suitable cam to go with the charger. During your testing did you test any bigger cams other than standard that will match with the YT non-adjustable RR's? The cast heads are going to be left basically alone cept maybe some mild flow work.
So any recommendations on a cam to suit a standard bottom end, mild head work, 36lb injectors, 90mm throttle body, non-adjustable RR's and a Terracharger? Would a 80mm throttle body suit better?

I'd maintain a stock throttle body and fit the super 6 36# injectors. Run a Super6 tune and you should see some nice gains whilst using an 87mm pulley.

A larger throttle body will require extensive tuning and you will lose airspeed through it. The stock throttle body doesn't prove to be a restriction until much higher power levels than you will see with your mods.

Hey William,

The Commetic or ACL are fine, i played with a Crow cam in my VQ and Matt used a Clive cam in his VS stato,
i went off Matts recommendations, the main thing is wider lobe seperation, Eg: 114 is good for supercharging, best thing is to call Crow or Clive and tell them your setup, they will custom grind you the best to suit ,
the Throttle body i ran was a factory bored out to 70mm, it gained 10RWKW over the factory 65mm, an 80mm or 90mm will be good, as it will never be a restriction with the 1.5L Terra charger

thanks for the responses guys...some things ive learnt the past couple of days talking with local engine shops is MLS type gaskets to be avoided if possible for 2 reasons, 1 is the block needs to be fully smooth for them to seal properly and holden blocks are a bit rough on the deck and 2 they wont warranty them unless they have been fully smoothed...so a Felpro that has the 'o'ring inserted in it has been recommended with boost applications and for sealing and now i can understand why...i might contact crow and see what they say about the cam...another thing ive learnt is maybe alloy is now an option after quotes ranging to $3500 for head work, cam and lifters...Micky the ABHA 5000-9EFI heads can be bolted on straight out of the box?...will they suit the Terra and 90mm throttle?...can they be used with the standard length pushrods and the non-adust YT R/R's?...do you sell direct or do i need to go to a supplier?...what deal can you do me for both the heads and throttle?
