ow... my over rated brain

An UDP will get you a 1 car length lead right off the start vs. a car without one. This is what i've noticed when screwing around at stop lights with my fellow P5'ers who have the exact same mods as me, minus the UDP.

The only diff I'm aware of between the turbo MPI and n/a MPI is the module.

That's what im thinking as well...cause if it is possible this way then I can always add the module later...

Wait a minute...Jeremy..are you planning on selling your kit? If not, then why are you doing N/A stuff..?

Kyle I might be selling it.....I'm just trying to have some fun N/A for now

You have a good start on ideas and "wish list" items.

Just be careful from assuming that simple bolt-ons alone and their cumulative HP/Tq gains will mean that 1+2+3=6. It's not necessarily the case. You need to get a good combination and tuning together to see a good cumulative gain.

Good luck.

I understand what your saying....that's why I was thinking about running the MPI to bring the modifications together to gain more..

A lightened flywheel will free up hp, but it'll be mostly in first gear that you'll notice it.

David, to find out if a TB is holding you back, you have to figure out what the stock TB is flowing in CFM, then find out the airflow needs of your engine.

The basic airflow equation is this: RPMcid3456

That equation is an extreme generalizaion, and another rule of thumb figure is 2.2cfm per horsepower. Now someone just needs to have their TB flowbenched.....I'm assuming it'll flow more than 230-260cfm needed for these equations. If not, then it's time for a bigger TB.....

Good info josh and andrew. Thanks!

I wonder how long it will take to uninstall and reinstall the TB....I'll be taking the P5 to the Dyno in May....wonder if I can get a run in and then install the TB and run it again to see the amount of gains with the bigger TB then we can see if it's worth it...

The tb is very easy to install. You might want to have a gasket for it incase the one on there gets messed up.

I have an extra TB thats why I want to explore this option and find out really what's the case....I'm also sending back a muffler to Corksport so I figure I can do it now all together...

I think if there is no increase for N/A maybe there will be an increase for F/I...

But we dont know till someone tries it out...I've heard all the reasons it wont work but what if its a great mod?????

Well time to call Corksport

P.S HURRY UP WITH THAT MPI!!!!!(thumb)

SpicyMchaggis · Mar 28, 2005

Jeremey, I've been running a honed TB for a year or so now. It's 56MM with a modified butteryfly. With mine, I noticed a bit better throttle response...but..thats about it really. It's hard for me at this point to discern if thats giving me any gains.

Fade · Mar 28, 2005

Did you have to port the manifold to get it to match? I can't remember how well the tb matches the manifold.

Heres a how to Jeremy. I would say 30 minutes to take off/install new TB if you have done it before.

Let us know,

Gen1GT · Mar 29, 2005

Hey, I never once said there wouldn't be a gain with the larger TB. There more than likely will be, but it might be a 6000RPM+ thing. My point is that the TB is key to velocity, and you would more than likely see low RPM losses that wouldn't be worth the upper RPM gains(until you're making good hp at higher RPM).

I'd be just as interested in a before/after dyno of a larger TB....

Fade · Mar 29, 2005

Just make the tb have a smoother transition from the intake by putting a chamfer on the lip. Then polish it out.

ozzie · Apr 3, 2005

i agree with twilight cams and then ecu i saw figures for the install of microtech lt-8 on a series 4 rx 7 and they got 37kw extra from the ecu after dyno tuning and no other mods plus by fixing mazdas dirty air fuel ratio they got 50 extra km out of a tank of fuel mind you that was a turbo and by controling air, fuel and ignition properly thay could wind up the boost 3lb so you wont get that much power.

Thanks Scorch70

I'm really debating weither or not to do it.....I got the wrong exhaust from Corksport...they sent a replacement and it was the same as the first(doh) ...but it sounds so sweet...Anyways I'll be looking into some other mods...as money permits..

No problem, glad to help out. I say go for the larger TB, for selfish reasons of course.

I really want to know what gains you make with it.

blueprotegelx · Apr 17, 2005

cams: no one has really bought the wagner cams from my knowledge...and i'm deciding whether to get cams or udp next...for now would u guys just recommend gettin the jspec intake cam? what about the exhaust? i heard it was practically the same as stock?

twilightprotege · Apr 18, 2005

no one has tested them properly i think is the answer...

get the udp for now. maybe, just maybe we may have some real info on the wagner cams in the near future???

j-spec intake cam will be enough for a decent amount of power, but you will need a custom exhaust cam.
