wow thanks for the help. This makes me laugh. If you wouldve read the whole post thats what I did (porting the runners) If you guys did this 1k times why dont you sell it? Instead you just sell the top?

Nice effort . . .have fun!

all i no is that i had a crawford and it is no where near as good as this one..........once u hit the gas u will no what i am talking bout .....an extream burst of hp and tq...so have fun doing ur test....
(to each there own)
*there is always some trying to take ur spot* step-up the game

keep up the good hard work rpm06g35

YOu all are saying this is amazing and such, but all i am seeing is the same few just saying how mike has made something awesome. Im not trying to bash or put anyone down, but i think i speak for everyone when i say, enough statements and lets see some action, as action speaks louder then words. Lets see some dynos or something before you keep going saying how great this is. Talk is cheap.

the funny deal is everyone wants to see a dyno. welp you are in fl right I'll let you drive the car. It doesnt matter to me. Anyone can do up a dyno sheet. The funny fact about the whole deal is that after an install of a top no one has had to get a tune. wtf after my set up your idle is around 500, the car doesnt even sound like its running at idle. just stating the facts. late mike

Seems like this thread is getting out of hand too fast.

All people are asking is if you keep on stating "this plenum is the greatest plenum ever", then just simply post a dyno sheet to back it up as a fact. Now, if this is only an opinion thread, then just state so. Regardless, no one has/had bashed your 'creation' as you guys have disrespectfully bashed on Crawford... Nor has anyone stated your plenum wouldn't work. Mind you, if people would take the same bashing approach I'm sure people would just call it a Modified-Crawford plenum.

Regardless, just like everyone else, I'll wait for the dyno sheets that'll back the statements.

this has nothing to do with the crawford plenum, mike didnt base his off of it.

I have seen this badboy in action. and let me tell you its the REAL DEAL. i havent seen any other plenum do what this one does. in ricer terms... its like adding vtec to the G. no lie.

im sure the next setup we can get a dyno done first then after

All of you are just nutswingers for your friend that made a plenum similar in design to Crawford's. Tell me in one way that this new plenum is different other than height? Theres nothing groundbreaking on this plenum, that hasn't been tried before. Motordyne has beat you to the punch on the ported runners as well, its called the Merv.

So to bash Crawford on their product is insane, Especially to the fact of how much they have contributed to the Z community. To say it's "amazing" and "its like adding vtec" , is just a step above ricer math with your miscalculated butt dynos .

I have no problem with the fabricator, I'm impressed with the workmanship and ingenuity, but for everyone else backing up the product with no real valid testing is ludicrous.

Theres a ton of dynos in FL, a ton of tracks there as well, and not to mention theres always a straight piece of road somewhere.

I said to put it in ricer terms for some of the brilliant people on here to understand the jump of power the car gains at around 3500rpms. only 1 person said a bad thing about crawford. i could careless about them and dont have anything bad to say. The only thing differeny that Mike has done, is combining the plenum and runner work all in one and for a great price. A dyno run will be done soon i bet, so get ur g strings out of a bunch nancy's

"fanboys" lmao.... cute man, real cute

That's great, and until theres a definitive gain on it by all means, i'm still on the other side of the fence. Nothing against you personally just the attitude that some are projecting in this thread.

We should change the name of this thread to the Plenum & Lower Collector thread. By the posts people are arguing that Mike is copying Crawford. The Plenum designs are similar, but the key is the porting of the lower collectors. That is where the gains are coming from in conjuction with a modified plenum. Mike is a master craftsman and I'm sure the dyno results will prove that this combo works to add HP. Keep up the good work mike.

money bro. I wish i had the time and money to work on **** then dyno it. Hell i wish I had my own dyno. But the fact is I'm in the military, have a chick, just moved last week and maintain 4 vehicles (2 hotrods a 4 runner and the g). But yeah sorry about the dyno stuff. I agreed to put a whole setup on a guys car in exchange for dyno work. He still hasnt brought me the lower collector to mill. Thanks for the comments mike

+1 on before (Baseline) & after (Plenum) Dynos. Or before & after Timeslips... It's the only way to be objective.

1. Please show me at the Motordyne website where is says that there Lower Plenum/Collector is Ported. The Mrev 2 is just a Non Rev Up for the Rev Up engines. Plain and simple.

2. The work Mike does goes beyond just a Big Fat Plenum Cover. He Matches, Ports, and Polishes the Lower Collector with the Lower Plenum or Upper Collector. This is more than any other company currently does with there MOD. Remember these are 3 different parts of the car being modified. Then after all this work he Mills certain areas on all 3 Parts to lower the combination of the 3 parts so they may fit under the stock hood. The result is a Plenum Cover that's larger than any other current design which still fits under a stock hood with a Matched, Port and Polished Lower Plenum/Collector and Lower Collector.

As soon as we find a willing 3rd person with a stock 2006 G35 and a time we can all agree to dyno... you all will get the results. This is going to be a learning experience since all three cars will be slightly different. Mikes 2006 G35 has a Matched, Port and Polished Non Rev Up Plenum. My 2006 G35 has the same scenario except that my Lower Plenum is a Rev UP. Just by driving both of them we have noticed a difference between my setup and his.

Please be patient as both Mike and I are as curious with the Dyno's outcome as you all seem to be.

No, the Mrev2 is not just a pre rev-up lower, it is in fact miled, i believe in the front two cylinders.

By all means again i am not trying to bash the fabricator but more so ranting of the support that hasnt been proven yet, to us anyway. Of course everyone is going to question gains, but to say this and that about it, with no valid proof is an instant raise of the BS flag.

Send one over to me, i'll give an unbiased opinion with dynos within the week of recieving it. MRC isnt too far from me, nor is turbotrix.
