Performance upgrades for 360

What are you guys doing for the following:

Exhaust, capristo, fab, tubi. Cat back or full header?
ECU programming, decent results or not worth it
Intake, BMC or other filters

Brakes, sticking with OEM or other

Suspension, thinking about lowering the car slightly, ~30mm. Any preference for mnfr for springs?

If possible just looking for a bit more pull, more sound down low and would like to improve the way the car looks by slightly lowering.

I have a beat on some very nice wheels from a 430 and also looking at iforged.

Thoughts?

 

I think cats and exhaust are going to be the most gain and best sound and bang for your buck.

 

IngPr and Trev360 has done a lot of upgrades.

Exhaust : matter of how much you want spend. Best option : change full exhaust to Headers(agency power), test pipes and muffler( your choice ).

Intake : Gruppe M

ECU reprogram.

no need to change spring to lower simply adjust coilovers .

Wheels : go wider and taller( if you like look) Iforged, HRE, BBS , OZ, ADV1

Then work on making it lighter

 

Awesome, thank you.

 

Don't forget TiMate titanium exhaust for the 360... Might be all that you ever need.

 

You can lower by adjusting the collars but it doesn't improve how the suspension responds. Several people have gone to a higher spring rate to reduce dive under braking.

I am thinking about adding Ramlift Pro lift system. Of course that requires shorter springs and I will raise the spring rate a little. Then corner balance the car. With this you can get a little bump on the front end to reduce the problem with driveways, particularly if you have lowered your car.

 

For improved handling and weight savings, a set of the titanium springs and shocks from the CS would firm things up by around 20% and lower the car.

Header back exhaust and ECU tuning will free up some power as well. Then put the car on a diet!

 

Dino,

you know how hard it is to find CS springs and things

 

Go with a lighter muffler and achieve weight savings and increased hp without the hassles of CEL.

I am very skeptical about any improvement with carbon air boxes alone on a 360. Maybe with CS ECU and CS airflow meters but you must remember the valve springs were changed and the intake got surface treatments on the CS.

I am also skeptical about claims regarding different air filters too.

You can save weight with lighter rim and tire set ups but need to include tire weight too

 

can't fully agree. depending on if its 2000 and newer he should go with headers to eliminate the pre cats. also, test pipes or high flow cats. And exhaust is a matter of how much he is willing to spend. Money no object then capristo. second, agency power or timate.

 

For other normally aspirated cars that I have had I saw minimal power increase with bolt ons. From experience you would typically need a tune to get the the most out of the changes. if lucky you can get 10, maybe 15% increase. I would be looking for balance, lower weight, better sound. Ideally some low end torque. Power wise, this car is similar to my e92 m3, the big difference is about 500lbs less weight.

Has anyone actually dynoed their car and saw first hand the power gain/loss from intake or exhaust?

 

BTW, the car is an 03'.

 

Most people feel the difference.

 

1+

 

Dyno is often asked and there are a LOT of threads with before and after dyno results. The gains aren't huge from any bolt on but 15% is still 60 HP so nothing to sneeze at. Weight is an easy target and make a huge difference. Shedding the first 100-150 pounds is fairly easy. Gets much more difficult, and expensive, after that.

 

60 hp increases from bolt ons I don't believe are real.
Ferrari only found 25 hp increase in the CS. I don't think aftermarket companies can find the HP they claim. They should be running racing teams then.

 

Did you at least tried it?

 

This topic comes up every few months. It seems we all have our own idea of what a performance upgrade is. For me an upgrade is something that changes the car for the better for the way I drive. In the 360, first thing I'd change would be tin the suspension, including lighter wheels. As far as dynos, yes they have their uses but lets be real, the 360 like the M3 is a high revver and if you are not on a track the only way your going to notice and extra 25hp (you will not likely feel a thing 0-60) is in the upper end of the power band. Why do you think tuners give you dyno results rather than real time (0-60 or 1/4 mile) changes, well because those numbers are so so small you would never buy a thing. Either supercharge the car and really feel power or take the damn thing apart (send it to me with a blank check it will be amazing though you could probably have bought a 458 for the money it wouuld cost you) and as someone said get rid of 500lbs, or even better buy a better performing car.

 

I think these are the most realistic and accurate opinions I have read on the topic and totally agree! Its true with any NA car, not just the 360, and other than a total race engine rebuild there is not a lot of hp there to be gotten from exhaust and ecu tune.
I do think though a new exhaust will give you the sound and sensation of more hp and might just be the cure your looking for.

 

I think it is not a huge difference but I'm sure it gains some good power, sound and response.
My car is totally another thing when I push it up to 9k rpm! The sound us just insane and really really feels the power at high rpms. It's there when a full exhaust system, full intake modifications and a very good euc's makes the payback.

I know that the investment is kind of high for the gains, but what the hell! I tune every car I own see the capabilities of each car. I'm done with my 360 until Rob finish a turbo system. In the while I'm ready to start othe project! A BMW E30 M3 with a S54 engine abd some turbo will be interesting.

 

They have emissions to contend with ...60hp is realistic . ECU, full exhaust definitely but the thing is its now useable now low. You do feel better acceleration

 

If you get the red key, it ass 100 hp. Seriously, do you think if extra HP were that easy to find that Ferrari (or other car company) would have done it. I have struggled with serious modification to get another 15 hp out of my Porsche 996 race car. I think if I added up all the +XXhp claims for all of the parts on it, it would be over 100.

Best way to improve the performacne of a 360? Sell it and buy a 430.

 

There's no substitute for cubic inches! Or cubic centimeters. The 430 not surprisingly has about 70cc more displacement and 70-80 more hp in a car weighing roughly the same. I don't doubt there are gains to be had in a 360, but they are relatively small. My car feels/sounds faster with Tubis but probably not that a clock would show. What I would like is some help in the driveability department. Once warmed up the car is sometimes not easy to drive smoothly in heavy traffic. Other than that, I'm not racing anyone (even on an track), so the 360 is plenty fast enough.
