My LPE DYNO Numbers

[KenP]

I just got the numbers back from LPE. I do not have a scanner, so here they are:
Max. Power: 358.5 @ 5200rpm
Max. Torque: 405.2
QTR Mi: 14.76 (uncorrected)
1/4 mi spd: 88.89 (uncorrected)
0-30: 2.13
0-40: 3.17
0-50: 4.64
0-60: 6.46
There was an odd spike of power @ 90mph to 444.1 hp.
The test was run to 136 mph. I do not think it is necessary to debate whether or not this truck would actually reach that speed. I seriously doubt it.
This was done on a 2 wheel dyno. This is done by removing the front shaft.
The numbers are remarkably similar to those posted by another member from another company in IN. using a different SC, the Whipple. I find that rather odd, but will not make any judgement, or assumption about that. But the fellow did work for LPE. Again, just interesting.
So there they are, enjoy.

Was there anyway to test it with the front drive shaft in place? I would like to see those numbers. Then I would believe in installing a SC.

[KenP]

Of course there is, but with a four wheel dyno. LPE does not have one. As a matter-of-fact, few places do in relation to the number of two wheel dynos. They are very expensive.

I am not sure I understand what you mean by your last sentence. Just look at stock times versus what I showed if you are concerned about power.

[CRUZMISL]

Awesome numbers Ken. I don't care if they tested it on a one wheel dyno as long as the before and after utilize the same procedure, you have an accurate measure of the gains produced.

I posted the numbers from DTE. I was searching around for someone to do the install and I was going to have them do my Z06 until it started burning oil. I since sold that and have the H2 but miss the power. Regardless of who is doing what they're both respectable numbers/establishments...always more than one way to skin a cat I suppose. You do have almost 50lbs more torque though. Also variables with dynoes can play a role. DTE quoted me a 0-60 time with a stock motor/tranny (Shift kit only)of 6.8 seconds so you're much better than that. HE also said when he was logging the truck he reached 123mph but it was REALLY windy

While there are pros and cons to both places, do you think you'd have a better resale value with Lingenfelter's name attached to the install? I know mods like that don't increase value at all but to the right person.....

While the resale did not play a significant role, in the purchase, LPE's reputation did. That is why I went with them. I do not think it can be questioned that who does the job makes a difference. If I said to a prospective buyer "Joe Schmo did the sc", well, I am sure that would not carry the weight LPE does.

I had the truck to 115 once. It was not as smooth as other vehicles, but not as bad as I thought it would be. The 136 was on the machine, it was not driven that fast in the open air. Now that would be a ride .

That 6.46 compared to 6.8 really adds up over the course of a 1/4mi. Then again, we are seriously held up by the wind against our barn like aerodynamics and only so much speed is going to be gained.

I knew it was you that made the other post, I was hoping to avoid a pissing match with you . Mission accomplished . I did not know how dedicated you are or aren't to DTE. I thought the numbers were interestingly similar. Especially since he worked there for quite some time. My two cents.

Now you need to stop talking about it and go get one.

Oh, if you do, watch out for Frank and Finally. They are constantly trying to get me to give them my SC by planting SUBLIMINAL messages within the body of their posts. They are very sneeky and you need to have your anti-sublime virus de-activator up to date. Also, do not let them know you have that program running, it would ruin everything.

[H2Finally]

What's subliminal about <span class="ev_code_RED">GIVE ME YOUR S.C.!</span> ?

There you go pissing.. er, showing off again..

[CRUZMISL]

Ken, no pissing match here. I think they're both great places. The only thing holding me from Lingenfelter is the added cost but $1k here or there who cares. I REALLY like the warranty and based on your previous stories it sounds like they deliver in honoring that.

I have to see how much in taxes I have to pay then we'll see. If I get it up the chute (likely) I may have to wait a bit.

What we really need is a vid of the 4 wheel peel

[Dan]

There goes Ken, talking about pissing whenever he can

I found some info from the guys at L.A.P.D. They have a 4 wheel dyno and this is their results of testing a stock H2:

<span class="ev_code_BLUE">We put our 2004 bone stock H2 on our 4WD Dynojet this morning and here are the numbers.

First Run: 154.86 total hp at all four wheels/234.74 total tq at all four wheels.

Second Run: 161.57 total hp at all four wheels/239.29 total tq at all four wheels.

Last Run: 171.52 total hp at all four wheels/251.46 total tq at all four wheels</span>

Great numbers! What mods other than a SC were done?

Jason

[KenP]

List of mods are as follows, it is quite extensive:

CNC cylinder head porting and polishing
Three angle valve job, set spring heights, assemble heads
Porting and polishing of intake manifold
Balanced rotating assembly
Pin fit pistons and connecting rods
custom hydraulic roller camshaft
Valve springs, retainers & valve locks
Forged pistons & heavy duty piston pins
HD rod and main bearings
Properly sized injectors
Yank custom torque converter 2800 stall
Borla stainless steel headers
HD automatic transmission rebuild
B&B Triflow exhaust
Flex-a-lite twin 15" electric fan kit w/interior auxillary on/off switch
K&N filter
Kenne Bell Boost-A-Pump (increases voltage to the fuel pump for higher flow rate and pressure)
And an Autometer Boost Gauge, it runs 9psi

I think that's it. I think that is enough , for now anyway .

Now here is the question of the day, and don't gag, I do it everytime I think about it: How would the truck run with a set of 35" slicks on the rear and the front shaft removed? Hummm... Certainly would look stupid, but it would get off the line great. It sure doesn't now.

I will have your supercharger Ken. Ooohhh yes I will!! Just remember I know where you live.

[Hummer Man]

Dan those numbers are almost identical to mine when it was stock!
