Cody said he hit 300 HP on a Gtech? shoot that isn't even a real dyno... his truck:1991. 5 4x4 Lucas injectors,[maxed pump}

My ol truck: 1993 4x2 Power wagon Injectors [extremely maxed}

both are 5-speed getrags... . who saw these numbers?? i don;t buy any of it---300 isn't possible on a factory VE pump with out propane or nitrous..... i know the guy has an aftermarket pump. The lucas's give 30 at most more horsepower than Powe wagon's... and he supposedly ended up 50 horsepower more than my old truck???i doubt it... . PIERS. . JOE DONNELLY what do you think... i know he's wrong:mad:
 
1 st gens

cummins power well ide say thats not enough

i think ill run 16 flat in my 1 st gen

next time out thats at least equal to yours

in my 1 st gen or how about my 1 st gen

against your 2 nd gen
 
I think it's possible. BUT, it has to be done with more RPM's, not cranking the fuel higher. Once you put in the Lucas hosers, and crank the fuel screw a bit, the way to get more is to turn it faster. I'm sure a fuel pump shop can find a way to get you 3200 or more before the governor cuts... and that should get you 300HP.
 
Codys truck runs real strong and I have to really hammer mine or he will beat me, I was there when they got back from the ride and the guy running the G Tech is the one that told us 300hp
 
I don't know much, but 300 is a lot for a 1st gen. I think that 200-250 requires a far amount of work, but 300 seems like Hmmm. I didn't think that a) our heads could take that b) we could fuel enough to do that c) Any one else got some ideas :)

Cummnzpowr,



Justin (jlatham) was with him while running the g-tech. I'm sure he'll chime in. Justin and I went in partners to buy the g-tech, and have made LOTS of runs with it. It was within 3. 5 HP of what I dyno'd at. Maybe Cody knows a little something you don't;) LOL.
 
I believe it. I got 37 psi out of my 93. I'd say its very possible, plus the other summer I drove the whole way from maryland to texas to touch Cody's truck with my gifted hand:D
 
B. . S. . ---power wagon is right {sorta} u need serious RPMS i mean serious RPM ... Wirenut, i made 40 lbs. boost in mine also. . trust me IF PIERS SAID IT CAN'T BE DONE, IT CAN'T BE DONE... END Of ARGUMENT... . and for those of you that got numbers from the G-TECH hope your numbers boost your ego's. . because it ain't right... . DEEZEL 1 2nd gen's and first gens are WAAAY different my good man,completly different beast they run very differently also. DRIVER'S MOPARS... Cody is fromTexas. . i think he should come out here and run his lip... {no offense anyone}... . just peeved that i spent all of my hard earned money studying the first gen fuel system and BOMB items... while some people have their mommy's paying for their I TRIED TO BY-PASS THE CUSSING FILTER:mad: :mad:
 
Cummnzpowr



You say some pretty nasty things for some one that wasnt there and doesnt know any of the guys involved or what they know. Do you have a lot of fun bad mouthing people?
 
for those of you that got numbers from the G-TECH hope your numbers boost your ego's. . because it ain't right



Not right huh. As I said before, the g-tech was with in 3. 5HP of what I dyno'd at (by the way, people also say that 400HP can not be broken with a small pump... see sig). The g-tech gave my friend a reading of 376HP, ... . he dyno'd at 375HP. Another friend got 297HP from the g-tech,... . he dyno'd at 294HP. Now, I understand that the g-tech is not completely accurate but it's very close. Try dyno'ing in one shop, then go to another and tell me how accurate one dyno is in relation to the other.



Cody is fromTexas. . i think he should come out here and run his lip



Watch it... . he just might beat you:D LOL,... . no harm intended.
 
I wonder if they got the truck weight correct? It is very important to weight them and the first gens weight is not as high as the 2nd's

I think we need to clear up some things before comparing apples and oranges.



First: does the G-Tech estimate engine HP, calculating losses in the drivetrain? Or is it merely trying to read ONLY the power reaching teh wheels?



Some time back, someone wanted formula to reach 250HP, and I did a really simple step-by step process of getting there.



It involved using PW injectors, a turn or two on the pump, some tweaking of the governor, and timing changes. By using published and dyno-proven numbers (not my own), I showed that 250HP is actually pretty simple to get. That involved only 10 or 15% more fuel than the stock settings, as I recall, and with the Lucas Injectors, you can get quite a bit more than that. Cleanly? No, but you can get it.



I do believe 300 HP at the flywheel is not unrealistic. 300 HP at the rear wheels isn't going to be so easy. But as yet, I have never heard anyone address whether the G-Tech estimates engine horsepower, or measures only rear wheel HP.



Your truck dyno'd at just over 250 HP, as I recall you posting, which means your actual horsepower was probably just under 300 at the flywheel.



So what can I say? This entire flap could be over nothing, really. It could be as simple as whether or not the G-Tech is meant to estimate engine HP or not. And, there are other variables. Even a slight grade will affect readings, as will wind, and even bumps in the road. Best to take all of it, even the dyno readings, with a grain of salt and a deep breath.



As far as Piers saying it can't be done... Experts said we could never reach 60 MPH, nor escape the earth's gravity, nor land on the moon, nor ..... well, the list is endless. As knowledgeable as he is, it's possible someone c ould prove him wrong :D
 
Guys, I dont even know what a G-Tech is or what it looks like, but I was also going to mention that if you do select the vehicle weight, this would be critical. My '93 weighed in at 6350 (thats with tools included though). I never did ask Cody what weight they used. Cummnzpowr, you are being awfully harsh this week, your supposed to save all this anger for the F*rd guys;) Why don't we get this thread involved with some technical discussion about this G-tech thing. I'd like to know more about it, then maybe Ill get one. :p
 
G-tech?

Well... anyone? does the G-tech measure ENGINE Horsepower or Rear Wheel HP?--and sorry for offending the light of heart gentlemen we have here, but some people have lost my respect big time for the way they have presented their apparent wealth of knowledge on a subject they THINK they are experts at:rolleyes:
 
Reading the post from cumminsgetme he stated the HP from the G-tech was within 3. 5 HP of what the rear wheel dyno showed.



Looks like he gave several examples to show the rear wheel HP from the dyno was very close to the G-tech in HP.

I would say the rear wheel HP is what the G-tech measures.



Like I posted before, the weight you input into the g-tech is very important to get the proper reading. If you input lower weight than the truck actually is the reading of HP will be higher.

The g-tech is able to calculate HP, 1/4 mile speeds and time, 60ft time, inst. g-forces, cornering g's, and braking g's. I probably left out a few things but I don't have the g-tech booklet in front of me. It uses an accelerometer to calculate HP at the REAR wheels. For 1/4 mile speeds it uses the time from initial take off as well as the acceleration (measured by the accelerometer). It then integrates twice to give an initial position which from there it calculates a velocity. G-tech claims that for best results you should make 5 runs then average your results. They also state that the runs should be made on a level road with few bumps. As for Cody's case, the conditions were not ideal, however I have run on much worse. I've tested the g-tech in many different conditions and it always seems to be with in 10 HP. All variables are considered in these calculations;loss in driveline, drag(dyno's don't compensate for drag),etc. The g-tech simply calculates these numbers based on acceleration, time and weight. It is not vehicle specific,... . that means you can get numbers for your Pinto too!! I'm real pleased with the g-tech,... . I'm not a firm believer in it, however I'm also not a firm believer in dyno's. I dyno'd at 423. 3 in Houston, then at 446HP in Las Vegas. I did however pull a few tricks out of my sleeve in an attempt to get 450 with the small pump,..... but my point is; how much of the 23 HP was gained simply by correction factors due to altitude. For me, both dyno's and the g-tech are simply methods of comparing aftermarket products and how they perform.
