Throttle Bodies... Come hither JT.

[John B]

I'm using the PT lifters and they seem to be doing fine. I have a crank scrapper and a windage tray that mounts to standoffs on the former balance shaft bolts.

I am building the same for my Rampage with the scraper, using a 2.2 steel crank with SRT 4 H beam rods in the hybrid. How did you make the windage tray though? Do you have pics of it?

No pics, sorry, I'll take some when I drop the pan to stop my infernal pan leak. I bought a piece of expanded metal from Summit and trimmed it to fit the pan with cutouts for the oil pickup and dip stick. I used copper tubing for spacers both above and below the mesh to position it just under the crank. I used the balance shaft bolts through the copper tubing with wide area washers on both sides of the mesh. I drilled a hole through the heads of the bolts and safety wired them together (I didn't put much torque on the soft copper spacers and didn't want the bolts loosening up). Not too difficult.

I now have my 75mm Throttle Body. YaY!

Anyone know of way to adapt throtle control so that you get less of an opening rate at part throttle, and more progressive past say 1/2 throttle? I imagine we can devise some sort of wedge or cam devise to combat the on/off nature of a huge TB. I may have seen something like this on an outboard engine...

I know you've seen that on an outboard(used to be a marine tech)...they use a cam and follower to achieve this. I suppose it *could* be adapted to a car, but it takes up some room...I think a better approach would be to make a throttle cable cam that is progressive...a bit of trial and error would have to be used, but I think it could be done..

re: the lifters; will the lifters from the DOHC Stealth/3000 fit in our SOHC V6? There is a company in Japan that makes a high performance lifter for the former at apretty reasonable price, if they will drop in.

I have a few questions after reading the thread:

Does the elbow hurt performance?
Does the air need as straight a pathway as possible from the TB to the intake?
Where does one get a 65mm TB?
Is it a bolt-on deal?

Thanks!

[B.A.P.]

The elbow is a restriction if you want to use a TB larger than 52mm.

No, but straight or smooth bends are prefered

No, unless you already have the modded intake with the elbow rework already done.
