turbo charger vs super charger

rave81

w/c among of these 2 do you prefer to use , and wat brand is the best ?

For aftermarket use, I prefer turbo chargers... much easier to install and less of a headache finding the right one. Boost is considerable and the lag isn't so bad depending on what your engine is and how well the settings were made.

I prefer superchargers for the same reasons Dinan for BMW, AMG for Mercedes, RTD for Toyota, Jaguar and other major aftermarket manufacterer tuners have.

Either one is good for me, although for out-and-out racing setups superchargers have my vote because of less turbo lag.

Notable brands for turbines are GReddy, Garrett and Mitsubishi. For superchargers I've heard Jackson Racing makes good ones. If you're going for a daily driver, just get a small turbo. Proper tuning will deliver boost at the midrange...perfect for overtaking oomph.

Fusion R did a turbo installation into my friend's VTEC City. It cost him PhP140,000. The turbine was a Mitsubishi TD04 (from the Pajeros) and Fusion R added an intercooler and fabricated their own piping. Price is a bit expensive but it was tuned very well, so it's worth it.

So far my happy friend's pushed his City to 190 km/h...in 4th gear.

did they decrease the engines compression ratio? turbos work well on low compression so they would maximise the boost without leaking it on the waste gates. im not an expert on turbo charging but i just got the thought of it.

a friend of mine have supercharging and turbo on the same engine. it is installed on a toyota. it worked well but hes having problems with the transition from supercharge to turbo. this guy is quite an extremist. hehe!

Mokkori

Well... since supercharger boost is effectively instantaneous, he can always tune the turbocharger to kick in at the higher RPM ranges... reminds me of a twin turbo setup... that's gotta be one monster of an engine.

I've read that turbocharging won't sit well with engines that have high compression ratios. I don't know all the details, but I think the City's D15B engine doesn't have the sky-high compression ratio of, say, a Civic SiR's or an Integra Type R's.

Only immediately noticeable difference was that the VTEC scream was now almost inaudible. Some say it's because my friend's turbo system and piping acted like a secondary muffler.

Twin-charged Toyota (S/C + turbo)? That's pretty great Only manufacturer I remember doing so was Nissan back in the 1980s. Your friend can follow Mokkori's suggestion. If your friend has the moolah to burn and the appetite for acceleration, maybe he can even spend on a turbo that's a little bit bigger for that definite secondary kick at high RPM.

For anyone considering a turbo or supercharger installation: I seriously recommend you canvass the pricing for a good fuel controller and its tuning. Without a fuel controller your engine runs the potential risk of detonation at high RPM.

Fuel-air ratio is usually kept constant at 11 parts air to 1 part fuel. Because a turbo or S/C pumps in more air into your engine than normal, more fuel should also go along with it. At high RPM, stock fuel injection programming might not be able to supply enough fuel into your engine---leading to a metallic grinding sound and potential detonation.

An adjustable fuel system controller, properly tuned, will abolish this risk. Reputable brands to look for are HKS and APEXi.

For turbos, I suggest that you invest in an intercooler and a waste gate system as well... a waste gate will help release excess boost and the intercooler will help keep the engine at safe temperatures... this is largely really good turbo upgrades are hard to install and maintain.

Compression ratio in turbos aren't naturally that high either. In NA engines, compression ratios tend to be high so making sure that the right parts are installed in the engine'll help keep it in one piece.

I've heard of a few turbo installation setups that do away with the intercooler.

As an experiment, Ford Malaysia fitted their Lynx RS A/T with a small Garrett T25G turbocharger delivering 4.35 psi of boost---enough to give the pocket rocket 50 bhp more than stock. No intercooler. Surprising, because the setup was orientated for daily driving and reliability instead of seeking out-and-out max power.
