A mass that accellereates and decellarates palces massive load on the material.
Thats why people start using steel crankshafts etc.
Weaker materials will just strech, buckle and tear apart.
You'll be picking up the engine parts.

Beleive it or not... thats why you have a rev limiter to keep the engine at a safe rpm below the critical failure point.

Doesnt stop you sticking it in 1st at 100mph...this will just lunch the engine for the same reasons

 

[franv8]

Normally there's some safety over the set rev limit (which is why some remaps can move rev limits higher than stock) BUT

Every part has different internal flaws, and the rev limit will be set so that most engines* don't fail. The second aspect is fatigue limits - these are areas where the force on a part won't cause it to immediately fail, but continued cycling in this mild 'overload' area will lead to catastrophic failure eventually. See DeHavilland Comet.

The third area is the ultimate strength a component has, that's basic the limit where any example will instantly fail, so yes, 1st gear at 100mph fits into this!

* of the same type

tbh i have always wondered what keeps the car at 7krpm and what ever it is why cant you change it to say 8k would it destroy the engine ?

Someone on the forum had their 1.8 chiptuned, think it has a raised rpm redline of 7200 rpm.
The US variant of our engine (R18A1) has more manufacturers working to get more out of the engine block and i've seen rpm's up to 8000 if i recall correctly.
So it wouldnt destroy the engine block but i dont know the effect on the long term. Higher rpm will mean more wear on the engine so it will probably reduce the life of the engine but by how much?
I'm still seriously considering to slam a few bits to the car, invidia catback exhaust and cai intake. Quiet a lot of tuning companies in belgium and the netherlands are claiming a chiptuning which ups the power by 12 tot 17 bhp and a raise in torque of 25 Nm. I'm interested to see the gains with the mods (an extra 5 bhp would be nice) but i need a company who'll do a before and after dyno to prove the gains first...
I already contacted a firm a while back and never heard back once i started about proving the gains on a rolling road...

That will be about right

 

[Loxy]

I know this thread is about the 1.8 but this is my dyno graph for my Type R. The standard redline is 8,200 rpm but when it was remapped it was raised to 8,600 rpm.

If you look at the graph the peak is 7,877 rpm, and then it starts to go down, so higher rpm does not necessarily mean higher BHP.

(Note this isn't standard vs mapped, it was a remap :thumbsup

 

[Woette]

I'm still gonna keep searching for some more oopmh for my 1.8.
Enough people have done it!
And no, i dont want it to be type-r fast or assume its easy to reach such bhp figures, i just want it to be a bit more unique!
Always the same people putting up sarcasm when it comes to tuning the 1.8 engine...

Mate... Ive never put up sarcasm regarding tuning the 1.8
I've helped with links and positively encouraged it... such as turbo options.. induction kits...
The sarcasm was directed at the companies failing to offer before/after dynos when questioned
:facepalm:

 

[coste1l]

have you considered the alternatives? how about less weight better brakes better suspension? having a fast car isnt all about bhp after all! some lightweight wheels, camber bolts with a FRS, braided hoses, better discs and pads and brake fluid will make a great difference to the car without having to chase bhp figures

 

[Relic]

+1... moer than one way to skin a cat.

10% off weight and unsprung weight will improve cornering/braking/acceleration by 10%.

A 10% power increase will just increase acceleration.

I'm with you - some extra bhp, that wouldn't cost an arm and a leg, would be more than acceptable ...

If the US 1.8 can be supercharged (and I'm certain I've read about it being done ?) then the Euro 1.8 can surely be, albeit different engine bay clearances may require piping refabrication ...

Find a solution, Woette, and we'll be "joint guinea pigs" !!! ...

....... better brakes better suspension? having a fast car isnt all about bhp after all! some lightweight wheels, camber bolts with a FRS, braided hoses, better discs and pads and brake fluid will make a great difference to the car without having to chase bhp figures

Apart from the lightweight wheels, I've done all that - it's POWER we now crave ...

Then its going to be little bits at great expense..
Camshafts, Head work, strengthening.
Then proper induction and exhaust kits + remap.
How much you gain over hondas work.. will probably be very little.

Water injection, Nitrous, Turbo or Rotrex will have to be the only other options.

None of this is gong to be cheap and you have to start asking yourself if it will be cheaper and easier to just get a type R ???

..you'll have to search amercian forums for best advice on the b18 work.

Your gonna need to bug hondaat like hell as well to get proper control of the ECU settings to match.

 

[Dr_D]

All I want (for Chrimbo, lol) is a little more low down torque.. I don't really need 300bhp at the front wheels ... it'd ruin my new bridgestones .... but I do want to make the car more driver friendly....

.... I'd also like it to stop lurching at low speeds... dammit, people think I can't drive the thing!!!!!!

From what I've gathered from USA sites, the 1.8 is quite a strong engine "ex-works" and can easily handle \ generate (say) 25\35 bhp more, with just a smallish supercharger and perhaps some ECU work ...

Type-R ? - no rear doors ! - and, then there is the 'uniqueness' that Woette mentioned ...

We'll just keep looking ! ...

Easiest \ cheapest fix ? - progressive springs - e.g. Eibach ...

 

[Relic]

If you have someone to test and do some R&D.
As I guarantee this is pulse tuned and may lose lots of midrange power.

The first thing I'd do is lose the resonator box diagram.
Lose everything from the Airbox diagram except MAF and Item 10 '45 bend'
Make a MAF tube to mimic that in the airbox, with cone airfilter boss.
So that it mates to item 10.

But thats me and Id need to see engine pics with dimensions to see what fits.

This is pretty much what I am attempting with the 2.2 for an SRI.
Space is considerably limited with the 2.2 but am unfamiliar with the 1.8.

Exhaust is another story

I'll be starting to look into it all after winter, probably around april.

I have quiet some things i would want to do to it.

Eibach springs, koni shocks, invidia exhaust, cai intake, lighter wheels(costly probably), wheel spacers (worth it?), new discs (not sure on type but probably aftermarket) and ferodo ds2500 pads

What i've read on the internet is that flaspro now also supports the R18 engine spec so i assume this will help in tuning the engine, but i'm not an expert on the whole matter nor do i crave the ultimate power.
Its been said, a bit more grunt in the low revs would be great, an engine tune on a N/A engine normally results in more gains in the low to mid revs so exactly what i'm searching for.
And on the "buy a type-r instead"-mather, i would be bankrupt due to the insurance and petrol cost... not to mention the extra purchase cost.
I've always adored my 1.8 despite its hick ups but lately its wearing a bit off so its time for a make over.
i'll probaly start a new thread when my 'project' is finalized and parts have been ordered so others can follow the progress or even aid in some decisions.

Keep us (me) posted, in advance ! - I'm especially with you on the Type-R costs - here, I'd have to pay around £50,000 new, + much higher Insurance and Fuel costs (all about +50% more than a 1.8 !) ...

I'm now happy with the suspension and brake upgrades, and the "cosmetic \ twiddly bits" (although colour-coding is tempting) ...

As the car is basically flawless, and it is unique, and has low mileage, I'll be keeping it for a few more years - so, time for a few more horses ...

 

[superficial]

I had a look into the various running costs of the Type-S and Type-R and didn't find them to be massively different.

In buying the car the difference was minimal (less than £1000 for equivalent age/spec/mileage). And yeah, insurance is more money, as is petrol/tax. Around £1000 /year more than the Type-S by my calculations (based on ~14k miles). Depends if that puts you off.

However, I can see that upgrading to the Type-R might be more expensive since you have to factor in the fact that the dealers will give you a far lower price for your Type-S.

Hi all,

Just picked up my first civic 09 1.8 es.

Lovely car! and i'm having great fun with it, but previous to this i'm used to driving diesls and am not too sure how to get the most out of this petrol engine.

I'm not used to rev'ing the engine so much so wandered what people found best? change up rev's etc.

Thanks!

Honda loves higher rev"s

at the risk of being jdm flamed to death take a look at rota wheels the p1 and subzero are light and cheap (and fake)
