Bottom end power

[BlakTegra]

I want more power in the bottom end of my prelude because its dead slow up until 5,5000 rpm. But once in vtec, its not too bad.

Anyone got any ideas?

[fadz]

supercharge :D

[jdmh22a]

Install a VTK controller and set it at 1000rpm lol joking don't do that..Depends on how much you willing to spend?

[[stealth]]

give us a budget... and we can recommend something :)

[redliner]

launch at 5,500rpm ;p

[azjs]

^^ agreed :)

Unfortunately don't demand too much from 2.2 naturally apsirated L's

[bigteethygrin]

try advancing your ignition timing to be a little more aggresive.. but not too far ok

[Cartoon]

Advancing the timing will help the bottome end out but how far will depend on the fuel u are using, 98 RON is the best if you are going to do this.

The main purpose of vtec was to have a fuel efficent car with power when needed so its not that your car is power less under the cross over point its jst maintaining low fuel consumption.
what modds have you done??? also opening up its breathing will help you get to the red line quicker ie. intake and exhaust.

What size wheel and tire combination are you using?

[redliner]

^^ as Dyno Dave mention about wheels, wheel size can determine your performance.

[azjs]

I think he was referring to if the wheels were had a larger rolling radius and were wider - this'd slaughter initial acceleration (e.g. a 215/35/18 set of chromes)

I've got 215/45/17s ( i think) and they're the shinny bling bling ones that came with the car. :o What do you getting at, Dave?

Im thinking of getting a CAI because I had a full CAI system in my dc2 integra and it was cool.

Fit a set of STD wheels back on and you will change your gear ratio's and the car will pull better down low.Other than that have a chat with azjs he knows more about modding Prelude's than most.

Agree with Dave, the 17s would be robbing you of acceleration. Why else do you see people fitting 14" or 15" wheels when they go to the strip. Its not just the rolling diametre but the weight of the wheel, having the extra weight at a wider radius increases the energy needed to spin them. 16" for the lude is perfect IMO, you'd be running a 50 series tyre which is plenty low profile enough for steering response and handling plus it's easier to accelerate.

Also remember that is it a NA 4cyl 2.2L after all. For me, the lude has plenty of bottom end, if I need to get a move on I use the gearbox.

[azjs]

I run with 16s, great for the street. Racinghonda &" Dave covered it beautifully

i asked the previous owner for stock honda wheels and he doestn' have them :(
I mean, the bottom end is so slow. I test drove another 5th gen prelude with stock wheels and that was slow too.

Are chromies heavier than stock wheels?

Yes the chromies are heavier than the stock wheels. The stock wheels are pretty light cast alloy, probably made by Enkei.

As for the 5th gen Prelude lacking bottom end, I think you've bought the wrong car mate. Should have gone with a Monaro, no bottom end problems with that car. Remember that its a 2.2L 4cyl car designed to produce high specific output, don't expect it to haul ass when you floor it going 2000rpm. That's what the clutch and gearstick is for. If you find yourself at 2000rpm in 2nd gear and need to get going fast then give the throttle a blip and stick it back into 1st. You'll sound and look like a pro. That's the joy of driving a high revving engine, working through the 'box, blipping that throttle, rev matching . . . I feel like a drive now.

hey man, u knew the lude wasnt that quick before 5 thousand...i thought u said u wanted to cruise?
if the bottom end was slow when u test drove it and u didnt like it, then why did u buy it?:confused:

[BlakTegra]

I know its a cruiser but it isn't just a cruiser... its a mix of sports and a cruiser. That's what attracted me to it (But mainly cuz it's a Honda :P). With me questioning about the bottom end is only a small part which maybe could be improved, but it's the overall package that I really luv.

I didn't say I didn't like Lude ever. I luv it to bits. As with most cars, there's always something you wish 'could' be better. I wouldn't mind 'improving' the bottom end like how you improved ur air intake system. That's why ppl mod their cars isn't it???

I'm guessing Honda wanted to increase fuel economy maybe...

[pornstar]

Tony, get urself a good flywheel and clutch, that will help

[BlakTegra]

sounds good, Andy ;)

[teggiboy]

yo tien!! ur gay...jk... still up for our lil cruise on tues? hehe... I wanna smoke ur lude with my type R...hahaha

[bored]

yea get smaller wheels

[Mitchman]

i say go the cheap option.... new darton sleeves, rods, 9.5:! pistons and a jackson racing/Eaton Blower with 12pound pulley.... hahah sorry did i say cheap? lol Ill tell you how much bottom end is to be had by september! should be good : p im sure that will fix the "boring" sub-5grand rev range

[buzz_civic]

Why not get a V-tec controller?

[Mitchman]

yeah just get a Vtech controler!. cheap as chips just ask BT revolution, apexi vpac II will let yoiu play with vtech engagement n air/fuel ratio etc, good stuff for the money i ses!

[dundas]

you mean VAFC II..
the downfall on the VAFC is that you want more power from it and you will require to have this Dyno Tuned and if u don't know the right wires.. you will need to have this installed too-
so thats apx an extra $500 on top of the price of the VAFC.

[WhiteAP1]

sounds to me like u want more tourque down low. Light Flywheel and/or changing the final drive should help with this. U'll reach vtec faster with either mod.

oh dude please learn things before u post.
vtec
vafcII

yes this is a good option, it is cheap ( 300 for the unit aint bad) ur then looking for 100 for install, or 150 for the plug and play harness and then 150ish for a tune. all up say 600, but can easily be done for under 500.....this was the best bang for ur buck mod i had to my car until i decided i needed something more serious and went standalone ecu

u can change ur high cam crossover and trick the ecu into changing the air/fuel ratio. thats the key with a piggyback unit like this, it tricks the ecu into believing something that aint happening, i did have some injector issues that did arise from the vafc2 tho, cant be 100% but i would put a 50 on it.

[CUL8R]

lol Ill tell you how much bottom end is to be had by september! should be good : p im sure that will fix the "boring" sub-5grand rev range
if thats the case i hope ur not gonna stick with just a vafc2 for engine management. please tell me ull go standalone.

i got mixed up with the name so shoot me! still got what i was talking about.

yes yes i am. Apexi power FC
did i spell that one wrong to? lol

[rev-tech]

The igition timing on my prelude just recently has been advanced slightly (not sure how much)
There was definately a noticable increase in power down low

As for other mods, simple intake/exhaust mods will help in freeing up some power
A lightlened fly wheel. i'm not sure if it will give you more power, but as there's less rotating mass it will rev quicker and make it feel like there is more power :)

[94vtirozguy]

a better clutch and lighter flywheel will help alot.
A bored out TB will also help.
As will buying a decent header.

boring TB will only help if it's causing a restriction to begin with. I've heard of a few cars that have had their TB bored and even lost power because the air flow was too slow.
much the same idea with teh headers

simple intake/exhaust mods are not getting the engine to develop more power, they are just recovering power by having less restrictions.
So if a manifacture designs very free flowing system, changing it will get very little power increase

[94vtirozguy]

correct but they also need doing at the start because any mod of importance needs a less restrictive exhaust and intake system
