Well its POURING out so i can't test it. Even though i tried. Install was a simple, the pump came with no instructions but its easy to figure out. Put the new pump in, car started on the first crank. Rolled it around back and forth just to make sure nothign leaks or stalls and it was fine. Packed the old pump, tools, and a flashlight and went for a ride. The car feels "different". Before underload at low rpm i mean sub 3500rpm it would kinda feel rough and struggle a little. Now the car feels silky smooth, i know its not in my head. It also backfires less, which is wierd. Side note, i have a 2006 r6 that was running lean after mods, backfiring liek crazy and shooting flames, installed a powercommander and tuned it, added fuel btw, flames went away and so did the backfiring. Back to the pump, i go 3k rpm in 3rd and get on it, about 4k it breaks loose and shoots to redline. Whatever, it did this before in the rain. So i tried 4th gear, car never broke loose in 4th. I get on it 4300rpm breaks loost and shoots to 6600ish, yes its spinning and yes i stayed on it, but heres the kicker boost was at 16psi at 6600rpm!!! I cannot confirm this as i dont want to die but i am going to the track tomorrow. I have done several data logged runs with the stock pump and fuel pressure maxed out at 1800psi and hovered aroud 1500-1600psi. I will datalog at the track tomorrow. I will keep this thread updated with graphs of fuel pressure vs rpm once i have comparrison. As for now, I like it, car feels smooth, and seems to hold more boost at higher rpms. Stay tuned.....

UPDATE:

Data taken 10 min ago. 4th gear roll at 18psi. As you can see the throttle doesn begin to close till around 6200rpm CONFIRMING THIS FUEL PUMP KEEP THE THROTTLE OPEN LONGER!. I dont know how much more proof you want.

This is proof of the car's performance.

damn that's alot of freakin $$$ for a fuel pump still! better than a grand i guess but geez!

well keep in mind we have get new pump housings from mazda so that we can rebuild these. thats a good portion of the cost right there.
 
but dont you charge a core fee? the pump housing cost from mazda has nothing to do with the $400 the upgrade costs.

If you look at it that way, the upgraded pump is $750.

I guess im just not sure what parts or labor are required for this upgrade that make it cost $400.
 
the parts to build the actual pump are over $350 retail. the pump housing retails from mazda for $400. the pump also goes through a tear down, cleaning and rebuilding process. plus we are not going to be the more expensive pump on the market if that tells you anything at all.

overnighting a pump to california, wow. well the soonest i could have one ready to ship is thursday. overnighting it is $100 for UPS Next Day Air

thats what i needed to know.
thanks ken!
 
Laloosh; how's the track? Any more good info you'd like to pass on to us speed freaks?
 
Laloosh sorry to update the thread for you but...i had to. My head is hurting.

On the other forum, Laloosh posted from the track. He hit.. are you ready..

12.9 at 111mph

with the fuel pump on street tires. I think his best times before were around 13.4 and 106. Not to be a noob but how much fvcking HP do you need to add in order to gain 1/2 a sec and 5mph trap with the same traction? This thing may be the best mod on this car so far!!

Holy crap I cant wait to hear impressions. Who wants one now?

Yup, the pump helps a lot guys. There is power to made even stock just adding the sucker. Wait until he gets back into his CPE setup and starts tuning it. He should hit a 12.6 with the extra power he will be making.
