going to get more power out of my car next week

[monkey]

I have next week off so going to inprove my cars breathing.
how you may ask and no not with a airfilter.

going to take off my inlet manifold and use my drimel to grind out all ripples and inperfections inside it then scotch brite pad to get it smooth.
this will give hopfully more bhp and throttle response than just a airfilter.
I will then clean it with carb cleaner and just to be shore stick it in the dish washer do not want metal filings going into my engine..
this is a old trick that still works need air to have clean unrestricted flow.
let you now how i get on.
have to go on how it feels do not have a dyno ha ha

[Muad_dib77]

Good idea - takes patience and a steady hand though... will you combine it with air intake?

If you could do up a quick guide that'd be great...I'm sure a lot of members would be interested in improving engine performance for little or no money

[colm_mcm]

doesn't a little roughness on the inlet manifold help?

[monkey]

thinking of putting in a panel filter itg.
then drilling a hole in the side of the airbox and putting a cold feed pipe in from the front grill.
this should keep the hot air out from the engine and also makes it like ram air you see on motor bikes.

[monkey]

you want very smooth surface for air flow.
if it is not you will slow down air flow and it will swerl and bounce around slow down.
thinking of putting heat resistant tape over the exhaust manifold to also reduse underbonet heat

[colm_mcm]

I always thought a bit of turbulance in the manifold helps. That said, I wouldn't claim to know a great deal about engines!

[monkey]

just for info inlet mainfolds are cast peaces and are not made perfect and smooth
I will post ether way good or bad but can not see down side unless i do not clean it right (boom)

[colm_mcm]

I know they're cast. but I've heard people roughing up inlet manifolds for more power.

[Kace]

Sounds like a lotta lotta work for something that I suspect will give little or no difference in performance or BHP. Make sure you do a dyno before and after and feel free to prove me wrong.

I'm sceptical as many people over the years have discussed how the FTO can be made better and more powerful - from seeing results to date, I'm not convinced that anything other than a turbo or stripping out weighty items from your car will improve anything.

[Myfeckin FTO]

It does sound like a lot of work for the negligible gain on a Tip GS.
If you're concerned about performance perhaps a manual GR/GPX would have been a better buy.

I'm in agreement here, guys have been tricking about with bored out throttle bodies on FTOs for a few years and any gains achieved were minimal (i.e 1or 2bhp on a MIVEC engine), for the work involved, I'd be inclined to leave well alone. A freer flowing exhaust and properly set up CAI to a panal filter would be the tried and tested route.

[soc]

I have to agree with Kace, MfFTO and CJ - total waste of time if you ask me - engine tuning for 99% of NA engines is just a waste of money for the gains. And having run one I can safely say that on a Tip GS the effort involved will not reap any worthwhile rewards.

Tbh, I never could understand why people will try to squeeze out a few bhp from lower powered NA engines - in real world terms I'd argue you'd hardly notice anything less than a 25bhp increase even if you do get slightly better throttle response. I can understand tuning higer powered NA engines for throttle response cause you already have the power there to play with - but even there you'll never really see many worthwhile benefits.

All IMHO of course so I'd be ineterested to see if you can prove me wrong

[johnny]

I have to agree with Kace, MfFTO and CJ...

I agree with the above and Soc.... smoothing the inlet manifold on a 1.8 GS is like using a hair dryer under water.. useless

What a great analogy

[Spitfire]

and its a common debate if you want a smooth inlet manifold (for better air flow) or rough inlet manifold to aggitate the air flow and make for quicker/better combustion (thats the reason they say having a rough inlet manifold is good)

soooooooooo, whats the point in doing anything?

get a GPX

[Muad_dib77]

If I had been blessed with a GS - I'd seriously be looking at dropping an evo engine in there - apparently it's possible.. apparently.. can't find any instructions or pictures tho

Sounds like fun....but a whole lot of wheel spinning! Way too much power for a FWD car.... 4WD conversion?

A 2.5L TT VR-4 engine is the way forward, its a much more straighforward transplant. Launch control would be a must to control wheelspin.

Just about this subject had a lad call into the workshop during the week looking for 3 throttle bodies to be bored out and larger butterflys but in ( celica, subaru and a gt starlet) finished the last 1 today..
Didnt get to have a chat with the mechanic on exactly what hes hoping to get from the modfication.
Just wondering would yea recommend me doing this to me own car or is it really worth it
Have pictures of me work
Stupid question how can i upload a picture with this message

Tanx cj theres the pictures of job anyways.

Unless you've a turbo its not really worth it.
