1/4 mile times

cant wait to see this!

I just talk to Dean on the phone. I was very wrong about the tires. He is runing a road race tire with 15psi. Do not ask I do not know why he has this setup. Anyway that is why he never gained much with the tires.

Yes you are very right about the intercooler. I think it is not helping at all. I think it is costing us right now. We hope to have a FMIC by the 16th. With tires and the intercooler we will see a mid 13 without any problems at all.

Thanks again


Later..Nick

With a drag radial he should be doing mid 13s as is. An FMIC on that setup would yeild a 105+mph trap. Let us know how he does.

14.3 with an intake and 11psi? wow

If I had better tires & motor mounts (wheel hop was terrible) that would've been a low low 14. I was still hopping after the 60'. One time it bucked so hard it slipped out of 1st gear.

 

[changedman]

wow, time for the mount GB!

 

[Emode]

im putting my mounts in today, wish me luck

 

[changedman]

good luck. be PATIENT and do it right

 

[Black Majik MSP]

It seems like the easiest way to tell when MSP owners first go to the track is when they start bitching about wheel hop. I just experienced this last night & after I get my wheels, TEINs & AWR motor mounts are top on the list.

Where would I be able to get better motor mounts while we're on the subject sort of. Nm there's a thread on this right now.

What octane fuel you used on those runs?

Those are good numbers, very good numbers.
15psi...on stock piston and rod, looks good. Ive seen up to 18psi on stock internals and thats the limit where the rods are sent south or the rod will open the piston in the middle...proven

I will test my car soon @10-12psi, no ignition management, just more fuel pressure on 100 octane. lets see if it holds

 

[spacemonkey]

A good 1/4 time for the mazdaspeed is 10 sec...but your 13.72@102.6 will do.

 

[Kooldino]

"With cutout"? What's that?

Groovy.

 

[Emode]

i think he means like a dump tube in the downpipe that opens up and runs straight out

 

[David MPS]

MPNick Can you give us more information about the MPI ?

thanks

 

[chrisjw85]

Yeah if anyone was doubting him believe him. My friend went last night in his wrx and talked to him, he wanted to race you man but you were 1 car away from him. That sucks. My friends wrx best time though was 14 exactly with greddy evo catback, injen intake, boosting at 10psi and I think that's it.

 

[KzA]

as far as the cutout, i think its like a Y pipe that has a valve in it, and one side of the Y goes to the cat and exhaust, and the other side goes to nothing(just open , like no cat or muffler) and the valve can be controlled electronically by a swicth..aka you have your cat and muffler on the street and on the track you have none..I am guessing this is what it is becuase I saw one of these devices on a table at Modern Performance one night while I was chillin there..maybe it was Deans..

 

[EvilMSP]

I saw them do that Y-Pipe on the tv show TRUCKS! and it was really cool. But that guy did it on a big 750+ HP Chevy.

 

[Striker187]

were the two extra injectors necessary for his setup? cause you can run the MPI piggyback with just the stock injectors correct?

electric cutout huh? was it quicktime's? or your own design?

 

[Bigg Tim]

Yeah, what kind of electric cut out was it, I want one. I am taking my downpipe off soon to put in a extra O2 bung,si this would be a great time to do this.

chrisjw85
why is you're friend running 10lbs on a wrx they run 14 stock...

 

[MPNick]

MPNick Can you give us more information about the MPI ?

thanks

The MPI Tuner/ mass air system, this is a system that we use to control the stock Mazda ecu.

The MPI Tuner piggyback/mass air system will let you tune your fuel and spark retard. If you are running less then 8-9 psi and never hit 5.0 volts with your MAF meter you can use our extra injector set up only. If you are running more then 9-10 psi or hitting the 5.0 volts then you will also need our meter.

It works like this, it is a piggyback so you must have stock ECU installed. The first part is for the stock MAF only. We tap into a few sensors and pickups. We tap into the TPS to read how much throttle you are giving the car at any point it time. We also use the crank pick up to read the rpm, we call it tach input. We then take the total crankshaft sensor output and send it into MPI Tuner. When it is sent to the MPI Tuner we then reprogram the output that is to go back into the stock Mazda ECU. We can retard the timing as much as 8 degrees. We have 128 points in our timing table for you to program your timing. We also can retard the timing based on boost load. We then take the MAF output and read how much mass air boost load we have. This part can be used for both adding fuel and removing timing. We then add two extra injectors in front of the throttle body. We have one driver in our MPI Tuner. It will drive upto 6 injector in batch mode. We then add fuel by programing the extra injectors.

I do not to get to long on this, I will post again about the larger MAF.


Thanks again
