Respectable HP....

My truck (my 95) is running again with A3K/5K twins on it (58mm/71mm) and I can't believe how drivable it is. Powerband is from 1,500rpm to 3,500rpm, and low smoke. Should be close to 500rwhp, and definitely still a truck I could let someone borrow without worrying. EGT won't break 1,200, even on high-speed pulls.

It's hard to beat twins for a daily driver, especially small ones.

That's good to hear :Cheer:

What do you have for fuel on the 95?

Agreed!
I love my he351 over the garret gt4294 (60mm/71mm) same thing, small twins great driveability and zero lag when u don't want it.

Was that with the 66?

Yes

A little background on the converter i fried, its a single disk billet converter I got for a 100 bucks, originally from ebay, surprisingly it did a good job! I'm the third owner, I actually raced the truck that it was in before mine when i had a 5speed, and he was not nice to it at all (it was a twinned 12 valve lots of low end torque) so this converter has had a HARD life. I definatley got my moneys worth!. Time to go bigger haha!

Garmon's injectors and delivery valve springs. Stock every thing else. Made 1600 on the pyro with the stock HX35, so the idea was then to turbo test until we got the EGT under control. Now they're ridiculously safe, so time for some more fueling.

Edit: timing bump also.
 
500 is plenty for a street truck that is actully used. north of 600 is either a ***** to drive without smoke or you drive it like you stole it and work on it all the time. I drive my 12v with the valet switch on all the time and when you do flip the switch it just gets sideways. I cant see being much fun to tow with this summer when anything more than 1/2 fuel just = spining tires. My truck is somewhere slightly north of 600 as it will drive over my 600hp load dyno but I cant see it being more than 650 and I wouldent drive it everyday.
 
I am shooting for 500 to 600 currently setting at 450 last month.... still got some more tuning to do still hazes some what but not bad.
 
before i melted mine down i dyno'd 992.9 @ ATS. couple weeks later drove it 140 miles to a sled pull and melted the engine down lol

i was DD'ing it for the couple weeks after the dyno till it let go

driving around at 860hp for about 6mo even in the snow wasnt bad, the ether starts were the worse part about driving it

"streetable" is a loose term and all depends on the driver
 
My buddy ran 550 the other day and drives everyday, he popped his stock turbo though but it works like a charm now

Hysterical post :hehe:
 
I would hand the keys to mine to very few people...and even less once I shorten it.
It can be a handfull now anywhere under 50 mph. I can't even remember the last time I went WOT under 70 mph myself. It'll blow off the tires at 1/2 throttle under 50 at will.
I think my personal limit for relatively maintenance free playing in a street truck is around 850. Anything more is almost useless. Fun...but useless.
I may actually end up detuning it some when it's a single cab and 5800ish lbs vs the 7600 it is now.
Mine isn't a 12V but power is power, right?

Id guess streetable implies near stock compression, small turbos and decent economy. That limits you a bit since the usual strategy for power is thicker gaskets, valve reliefs, and lots of boost to clean up the fuel. Kills the low end power and economy.
Im trying this from a different angle.. tight converter, stock compression, o-rings and 625's to keep the head sealed and hamiltons cam and head for a little extra flow.
looking at carl's super over turbo setup to make enough air to keep the low end clean while I run enough fuel to have some fun on the low end too.
motor will get swapped into a superduty at some point, so I want to make sure I can pass emissions on it.

this is a good point

650-700 will be darn good for a supercab or four door long bed 4x4, but take into consideration a frame like his, or mine 2 door long box, and 550-600 would be right around the equivalent of that in a lighter truck..

850 in a street truck, amazing, too much for me tho... IMHO... im good with the 650-700 i want in my 12v.. but who knows i may end up settling for 550 or so...

i started my cr.. and settled on a smarty on 5 with afe and magnaflow.. but that truck is just that, my working truck.. tows ALOT....

What chargers are you running?
 
A 62/71/14 over a 1.32 S478
850 is about the outter limit for those chargers living a happy life.

whats so funny?

part of the melt down was driver error but the engine lasted about 20K miles more than expected...long story

didnt care the engine let go, kept throwing parts at it till it melted down

I love it, 850hp on 450k engine and you daily drive it. It is hysterical that it held up! If i had enough room in my signature I'd copy the whole post and put it there :hehe:
 
Allright....so I haven't dynoed with the compounds yet, but expecting 470-500....

Any ideas yet on how to hit 600 and maintain this level of smoke??

I don't want to turn it into my 89......

I was thinking...more timing? Bigger injectors? Keep the stock DV's maybe, or some 024s? They seem to be pretty clean. Bout time for a lift pump too of course.
 
I did a very clean 564 with 5x.012 and stock 131 delivery valves and 26* of timing (all on a stock head gasket). I believe you have enough air that you can get away with 022 or 024 with 5x.012 and make 600. Your gonna need to tune the crap out of it to do it clean though cause once you get away from stock DV's low end smoke increases substantially.

In my opinion you should hit the rollers with your injector and dv combo now, I think you'll be surprised how well it runs. Then start changing DV's for more fueling instead of jumping up on injectors. It's cheaper that way too.
