G'day everyone.
Cheers for all the available info on here, very very helpful.
I'm writing from Western Australia, it's a big state about the size of CA to WA to ID to AZ, and it's mostly a big desert sandpit.
Anyway, I had the pleasure of spending a couple of months last year driving around the USA. You guys got a fantastic place there, wish I could of stayed longer and seen it all!
Weapon of choice was an '87 N/A E350 with a 6.9 C6+GV and 3.55's in the diff, 180k or so on the clock.
I thought it was pretty sweet ride until I hit the Rockies. Mate, the shame in slow lane was pretty unbearable. Fair enough the pump wasn’t tuned for altitude, and it made across 1/2 a dozen times, and I never had any major dramas. Pretty solid really.
Regardless, I liked travelling by van so much I decided ship it out to Oz.
We get the pickups down here, but no vans... dunno why, this country is made for driving.
Anyway, I've been planning to freshen it up, fuel system, turbo... luckily there's nothing down here you could really call a mountain, and everywhere is pretty much sea level... but the extra performance would be good all the same.
I’m converting it to 4wd, with a dana 60 front, 271 transfer case, 35 inch tires.
Fully set up as an offroad home away from home I expect the weight to come in around 11 to 12k, which is what, about 4k more than the pickups?
I was curious how you guys with turbos, 3.55 axles and 35in tires find the acceleration between 65 and 80 mph?
See, we got no interstates down here and our highways have only two lanes, one each way. Most of our produce is trucked around the country on big road trains with up to 4 trailers travelling at 65, and overtaking as quick as possible is a big priority.
Current tranny, tire axle gears put me at about 2400rpm in 3rd at 65mph stretching out to about 80 at 3000rpm, seems to me just at the beginning of a sweet spot for power once turbo'd. And with the gv kicked on should settle down at 2000rpm to cruise at 70mph.
The other option I've been considering is an E4OD transplant + the GV and 4.55's in the axles.
That'd put me in the stock 4.10 and stock tires range. However, I'd be overtaking the road trains in OD, making the final drive ratio pretty much the same as the 3.55's, so I guess the acceleration through 65 to 80 would be much the same… I s’pose.
Being a van… probably looking at a slightly customised turbo… or the old hypermax kit.
Probably not such a bad pick anyway being non wastegated, and my need for high rpm power. Besides, I emailed banks and ats and nobody replied.
Max at hypermax did say it might be possible to fit the pulse van kit, if I was prepared to massage the doghouse a little. Sounds possible.
Anyone run the old hypermax, and then the pulse setup and have any opinions on the difference in performance?
Anyway, cheers
