Okay, I will start with a little background info before I show my results. My vehicle and season info can be seen using my stats button below but I will start with my scores throughout the year:

3X in Niagra Falls in march:

159.1 w/four 40.1s

3X in Carlisle in may:

157.6 w/two 40.1s

3X in W. Viginia in may:

157.6 w/two 40.1s(losing score so stats only show a 156.?)

The last show disappointed me alot so a couple weeks ago I took a trip to Maine to visit a couple freinds(Rooney and Bob). The goal was to test with some different equipment to see what might work best in the van. First we got base numbers with what I already had and found that Rooney's mic was the stiffest I had ever been on by alot. Then we swapped out my amps and subs, basically comparing two Sampsons to my two 40.1s. The following results are with each amp at .25 off of one CS9000 in street max style(vehicle off for runs).

The best numbers from the Smapson:

159.9 the voltage dropped to the mid 9s - we clamped and measured just over 4500 watts per amp.

We then put the 40.1s back in at .25:

159.27 the voltage droped to 10.16 - we clamped and measured a little over 3500 watts per amp but not on this run(measured the power at 158.69)

I am not saying anything bad about the Sampsons because they are beasts and work great if you have battery power to back them up, I am just showing how good the 40.1s are! I waited on posting these results because I had a show on Sunday, I did a 159.8 in StreetMax!!!!!

On a side note, if anyone has any spare 40.1s they would like to send me i would be more than happy to go to Carlisle in August and break the 160 mark!

Where are you located. I'm not competing this year but I Rooney and Bob are definitely my competition area. (I'm in upstate NY). Just curious as I'm gonna need help next season going against Rooney in SS1-2 ( I think it's Rooney.)

Good feedback and results!

I think the best test will be 4 40.1's vs 4 7kw's!

When the 40.1 came to be it was a market that need to run 4 amps off one battery.

Street B - 4 amps 1 batt.

Street C - 8 amps 2 batts.

SM 1-2 - 4 amps 1 batt.

SM 3-4 - 8 amps 2 batts.

Okay, more test results. These are on a new meter so the head to head scores are more important than my previous scores compared to my new ones.

Background:

I am preparing for DB Drag racing World Finals were I want to win the US and place well amongst the top Europeans. After seeing some amazing test results from Terry Brocks and Jeff Brown I decided that would try the Stetsom 7KDs in the van. I bought a used pair and proceeded to modify them for maximum current. I then installed them in the van with the following results:

159.6, voltage dropped to 9.89

The next run produced a 159.5 and alot of smoke, one of the amps lost a board. Disappointed I reinstalled the 40.1s and tested again, here are those results:

159.4, voltage dropped to 11.03(leaving me plenty of room ta strap another pair in). I will also be testing on the mic I had previously been using to see what if any difference there is from mine.

Again if anyone would like to help me out I would really like to run four 40.1s at Finals, this is hard for me to do since I dropped all my amp money into the 7KDs which I can't even sell now to get my money back.

I am in Utica, NY and would be happy to help you out. Sorry I didn't see your response sooner.

Some serious numbers!!

I think that's the cause of the smoke

I can email you a couple tweaks for the 40.1 if you want to try to get a bit more power out of them

I am always looking for more, send it to [email protected]

E-mail sent !

I'm curious how that mod is going to translate on the meter

Is there any down side to this mod, is it dangerous for the amp?

Is there any down side to this mod, is it dangerous for the amp?

No downside. It's like running the amp on a 16v system

Only thing dangerous is scratching the wires on the windings. If you can do everything carefully, nothing bad should happen.

Both amps in the pic I sent you were eventually modded in that way and one has been used at 4 comps untill now (3 of them were 30sec music runs) with no problems what-so-ever

im still like learning about all of this stuff.... how do these batteries compare to the powermaster d3100?

The CS9000 is one of the best batteries for Street Max, the output is on par with the other monster batteries under 800 cubic inches(batcap, DD) and can be had for a few hundred dollars less. It is however very expensive, you could order one from Cactus for $900 plus shipping. I wouldn't recommend it for anything other than DB Drags street max class however.

Did you mod the amps ? I'm really curious to see the results after the mod

No mods, I talked to Nick and he said it wasn't worth the risk.

Booo

It's the same risk as running at 18v. I haven't measured the pair in the pictures before the mods. And don't have a sub capable of taking one of the amps

Actually the danger lies in performing the mod, but I might have that problem solved as well so we will see. You could always send me your two and I will send you back mine, then you could just perform the mod again.

I agree there is a danger in doing it.

I'd send them to you, but shipping is around $300 and you'd have to wait about 2 weeks...
