OK. Mevi is getting installed next week. This will handle my high end power. I know the max has good mid range power.

I need advice on what I can do to get better low end power.

Here are my mods:

Frankencar Intake
Warpspeed Y-pipe
Warpspeed High flow cat
Custom Flowmaster exhaust
H&R Springs
KYB GR2 Shocks
Exedy Clutch Stage I
18" Excel Rims (Im not changing these...i know they slow me down at low speeds)
MEVI (I will be installing it soon)

I know about headers....but 699 for 7-12 hp....or even the ecu programming for 599 for like 10hp and better air to fuel ratios thoughout the band....dont seem like enough gains to warrent that kind of cash.

Any ideas?

 

get underdrive pulleys (UDP)...motostorm GD has it for $90 shipped i think. u can easily get around 5WHP across entire RPM range

 

If you want to gain some low end back with the MEVI, you best bet is to get the ECU.
It will help in the low end as well as throught the power band, and if your spending the cash on the MEVI, you might as well take full advantage of it by getting the raised rev limiter.

 

yeah you sould def. get an ECU, yeah you gain 10hp at top, but think of the extra 600rpms you can travel through now. Also, you gain quite a bit of low end too, gets it almost back to stock.

If you really want low end power, get an 00vi + ecu. then you are rocking.

 

ECU will give you added midrange response/hp, not only "up top". And if you did not get the rev limit increase, you're not gaining anyting on average as opposed to the MEVI, vs USIM ... The extended rev limiter gives a better average HP.

So in short simple terms, the MEVI+No limiter gives the same AVERAGE hp # from 2-6.5k, whereas when coupled with the extended rev limiter gives a better overall (average) gain.

No MEVI should be done w/o an increased rev limiter. IMO.

 

I don't believe the UDP benefits 4th Gens and is probably a waste of money. Others can chime in on this.

 

ECU is what you need. And the UDP is a waste of money for us. It was either Dave B or SteVTEC that did the dyno and 1/4 run to show that it had 0 effect.

 

Put your stock intake back on...

 

Open it up a bit to make sure you don't loose any top end. Remove the resonator from under the battery tray and drill a few holes in the side that faces the inner fender wall. This will give the stock intake another source of air to breath.

 

Dave ran a 1/4 mile with and w/o only to get identical results.

 

I've heard this before....does this mean i have to get rid of my k&n and go back to the stock filter as well or can i use the adapter?

 

There're hoards of people here who claim the stock airbox, hacked or not, is the best intake system for our cars. You can use any panel filter you want.

 

anyone with a stock intake laying around that would like to sell??

I sold mine

 

since you guys are talking about mevi's a little, i just put mine it but need to wire it up and have no directions. If anyone could tell me how to wire the harlan and map/baro switch, that would be great. also, which was is open and which was is closed on the mevi?

 

Why don't you try looking at the numeous MEVI FAQ threads ... Can't go wrong there.

 

i just took mines out of my 97 if your still interested

 

yeah i would like to see the dyno... UDP is worthless..

 

should've gunned for an 00vi...

00vi doesnt sacrifice low end power....BUT...since u went with a mevi...go with the ECU...that way ur MEVI is effective for an even longer time since the redline is 7.2k...besides i thought it was more like 15hp in some areas for the ECU...

 

i saw a 6whp gain and 5wtq gain after installed my pulley on the dyno.

 

Others have seen no gain at the track

 

Have you dyno'd at all? That might help us see how you compare to other power curves for lowend. Here was mine w stock ECU/IM and with 48lb heavy wheels.

 

I put my stock resonator back on, removing the frankencar midpipe and saw a definate increase in low end tq. I still am running the K&N filter for the topend, its a great combination without all the useless noise..

any disadvantages?

 

Well with only a 5hp increase, that really isnt enough to see a time slip difference at the track. You will prob feel some more response, but its not going to drop you .1 or .2 at the track. In the end every bit helps. Just like using the stock resonator over the mid pipe, it feels way different but track times will be the same.

ECU will help out low end, 00 VI would have been better over MEVI too for lowend, but too late. UDP will "help" put stock resonator back on intake, or stock intake all together ( I refuse to because I love the sound) Nitrous helps me out with the low end

 

5 hp could also be a variance in conditions of the 2 different dyno days.

 

That is entirely possible too, but the pulley def cant make you lose power. Its less rotational mass on the crank which has to help. I do believe the claims on the sites of "11hp" for the max with a UDP to be way exagerated but I do believe it helps. I'm going to be getting a motostorm pulley soon, so I'll see for myself too.

 

I have heard its almost impossible to gain low end with bolt ons. Besides maybe a turbo or sc. And that increased displacement is the only way to get serious low end gains.

 

Agreed, there has been many, many threads on this subject and "correct me of im wrong" but a UDP has not been shown to give ANY HP gain. only a quicker rev. This has been my experience as well - better (faster) rev, no HP gain noticed. If i were you, go ECU all the way bro.
