Its Time To Push The Limit

Bad luck about the nitrous Luke.
Well done with the new P.B.
Sounds like you fixed your Auto problems. Well down.
When's the next trip planned, i might tag along.

ps, we are 111mph bros.. haha

No I didn't over rev it, I think I may have lost spring pressure. I will check it this week and see how we go. Maybe next weekend I will go back out, if not the weekend after. Heathcote runs every Sunday now.

Here's what No.3 Inlet pushrod looks like!!!! :

Lets hope there in no "piston to valve" issues after that. What is you shift rpm?
Head back out next weekend, and we can make it two XDs with another set of PBs.

I shift at 7500rpm.

The pushriod let go during a burnout, I as holding it a 7200rpm during the burnout.

Yes piston to valve contact is a something I am keeping in mind.

Oh and I think I need to change diff gears too, cos I am trapping at 6600rpm.

I was crossong the line at approx 5800 rpm. I need to change out my 3.9 gears. You running 4.5?

[Work Horse]

Oh well Luke there is always next week, and the week after that, and the week after that.......

Just a bent pushrod is nothing, I bet it gave you a fright!!

Keep at it!

I am running 4.33 gears at the moment. I might go 4.55 or even 4.88.



Workhorse, yeah just a bent pushrod, if the lifter had not popped out I would have replaced it and kept racing. Now, I will try and find the cause of it, as I didn't over rev it.

Fun and games!!!!!!

Good effort Henry with your NA time!. Can't wait to see the Nos times.....lol

[xdclevo]

You should be able to get that lifter back in without removing the manifold. After cam runin, i usually SUCK a few out with a magnet for a quick look. Bit tricky, but not too bad.
You may also want to keep those gears when using gas with the mph you will run.

[protd]

i run 4.56 gears and crossed the line at 7800 changing gears at 8200 in a xd..
hope that helps u decide on a gear ratio xdslider

[Qwikcorty]

changing to lower gears will suit n/a, but with an extra 100-150hp your current ones might be fine. what size tyre do you use now?

[Gammaboy]

7500rpm on 3 piece pushrods? brave...... I have ZERO faith in 3 piecers after I opened a packet of pushrods and had a couple of the ends roll out by themselves...

I am running a 26/8.5/15 's, like the one's you got off me.

[brenx]

4.3's should be right, even 4.11's should be right. I used to cross the line around 6600 with 4.11 and 26/10.5/16 slicks. I'm now crossing around 7000rpm with the same gearing and tyres. Just add power Luke ;) Press the button and you'll find your either close or spot on.
