Sounds like you have been busy.Will be a stand out ute when everything comes together.

Any questions on the W/M install just ask.Your boost pressure will be back to normal….and cooler.

Never been to Summernat’s.Have to make the trip down one year look’s like a lot of fun.

Thanks Senator.Hopefully it all goes well.

HDN05L Cheers mate.How’s your ute progressing?

Went for a drive the other weekend and it is too frustrating having limiter set at 5200 rpm.Time to sort out extra fuel.Have decided on another 044 activated by boost at 7 psi,500rpm below it starts to lean out.I don’t want both pumps on all the time.I only need the other pump after 5200 rpm so no need to heat up the fuel and draw another 15 amps…[Read more]

Cheers.I’m happy with how the ducting came up and it handled the boost just fine.Also glad i recirculated the bypass valve as you can hardly hear it dumping after boosting.Traction is always limited to the right foot lol.

Thanks,i was happy to leave the dyno behind the wheel…you never know these days can end….12 psi on 10.1,  pump 98 and…[Read more]

Thanks.Yeah it will be good to get out and drive it,even if it is only to 5200 rpm.

Well, nearly 2 years later and dyno day has arrived.Took a couple of days off work to install injectors,re assemble ducting,mix W/M,oil change etc etc and cross fingers for dyno session.Also had a bloke out to mod plate all the area’s I’ve modified over the years including the blower,it was a long list…

After a couple of hiccups including a…[Read more]

My mistake,thought you were burning pump 98.No need for the spray then.

I had vague off centre steering,suppose i just accepted it as how a 20 year old car behaves.At this stage i had the usual king/koni combo.Added adj sway bars and had a play with different settings.I found the harder i went on the settings the sharper the steering became.31mm setting was too harsh so didn’t bother with 32mm hole.30mm or the…[Read more]

Considered turning on the W/M system to help with the extra timing?Just for detonation control i mean.It looks like it’s responding really well to only one degree.The spray would allow another 2 to 3 degrees with a good safety margin…..might as well add a few more lbs boost…..and now you have zero traction ha ha.

I’d have a permanent grin on…[Read more]

Can’t say i’ve ever come across a 402ci Holden with factory block,can be done but would require a 60 thou over bore.Not greatest starting point for a strong bottom end i would think.

Agree 370ci would be the best balance of torque vs revs.Shame C.O.M.E. or Scat don’t make them.

Sounds like you have it sorted.Engine bay heat won’t affect the connection.

If you doing more sparky work on the car in the future grab some shrink wrap,it’s cheap and is great for say joining wire when spliced and soldered,never come apart.

I have twin earth wires,you might as well make it as good as you can while your at it.

Just a suggestion.Crimp the wire so it’s slightly extends through,put some solder on the wire so it’s now held at two points on the connector.Now slide over some shrink wrap so it covers the crimp join and down the wire say an inch,then heat to shrink.Will be a…[Read more]

Two wires to + battery post from each relay,then from each relay the wires connect to the two + terminals on the fan connector,so each wire feeds one fan motor individually.Mine are switched on by the Autronic  at 183 F and off at 180 F.They should turn on at their fastest speed wired this way.As the diagram shows it requires another sw…[Read more]

I have the AU fans and they are wired to come on at full speed when switched on.They draw 50 amps at their fastest speed.The auto electricians originally only used a single relay and it eventually melted that and stopped the fans.These fans work really well but they draw a heap of juice.

Your 40 amp feed wire might be on the light side.Mine has a…[Read more]

Stout engine this one.Just shows if built right and tuned well the old Holden can make good H/P.

Fingers crossed the extra timing doesn’t increase the cylinder pressure to a point where the heads start to lift. Tuner says to me “This thing loves timing, 32 degrees before it stopped making power we will leave it there”The engine leaked coolant…[Read more]

Thanks Cava.Yes definitely needs to be shielded from the stones/water run off as tyre is close when turned.

Cheers.Yeh I’m keen to tune it asap.I want to feel the boost lol.

Had to come up with some idea to brace bracket as there was no room for the Vortech brace which works well but loads the crank snout even more,not good for my Harrop…[Read more]

Your right,lot of work.Did that three times on first dodgy engine build trying different head gaskets,engine out twice also.Would be nice to have the extra head bolts.Good luck with the new tune.
