How to drive a turbo?

Guys,

I often hear people saying that they know how to dirve a turbo and the terms high load, high boost, low load, low boost,...

I have driven manual cars all my life but never a boosted one.

What is a proper tecnique to drive one?

Should i go gradually on the gas or stump on it?

Should i avoid pushing the pedal down in 5 gear at 50 mph?

Does high boost means that you are all the way down with the pedal and high load means that you have low rpm?

Thanks

Don't put a heavy load (press the pedal all the way down ) on the engine at low RPM's.
 
Low RPM + Boost = High Load
High RPM + Boost = Fun

Just don't boost much in 4th and 5th and you'll be fine. If the car feels sluggish or is bogging, its probably because you're in too high of a gear at too low of a rpm.
 
even if u slammed ur gas pedal at low rpms lol wudnt do much neway, at least for my car... it seems fastar if u ease it

Boost just means how much pressure your intake manifold is seeing. If you get a boost gauge you can see how much throttle it takes to get into boost, or not. It is related to how much you press the throttle, but it's not completely linear, I mean, I can reach maximum boost at less than 1/2 throttle.
 
you can make rpm and boost somewhat linear if you dont get throtle happy and just kinda ease into it.... (rockon) (rei)
 
boosting is fun. this is my first turbo car and it's alot of fun to drive. i mostly boost in 2nd and 3rd gear.... unless i'm on the highway, then i'll downshift to 4th. boosting in a high gear like 4th or 5th when you're going slow is putting alot of stress on your tranny and engine, so that's not a good idea. there's less stress on an engine when it's in a lower gear and in high rpm, than a high gear and low rpm.

I like to gradually get on boost, i don't stomp on the gas all at once. when you're downshifting in traffic or before a turn, make sure you rev match. meaning brake a little, change gear, while you're changing gear, blip the throttle to bring the revs to where your lower gear would be, and then release the clutch. so if i'm going 30mph in 4th, i'm at ~2000rpm, and i downshift into 3rd, i should bring my revs up to ~2500rpm before i let go of the clutch. if you do this right, you shouldn't even feel any jerking, just silky smooth downshifting.
 
Try to stay out of boost below 3k rpms and try not to floor it in 4th or 5th for an extended period of time (although I do it a lot on the race track and haven't had any issues so far).

The best way I've heard it explained is like riding a 10 speed bicycle up hill. You're the engine powering the bike with your legs, and it's much easier for you/a whole lot less strain if you go up the hill in a lower gear because it's easier to pedal. It's the same way with a car, it's a whole lot less strain if you just downshift.

I noticed that if i reach 4000 rpm progressively I will not notice the hesitation but if I go pedal to the metal i will notice that a lot more.

Basically I should put pedal to the metal after 3000 rpm and enjoy until 6000.

When I am in the Highway in 5th and I am doing 85mph at 3200 rpm I just push the gas to accelerate anddo not downshift.

If you do not want high load what is the best way to start from a stand point fast?


Just gradually or revve it to 3000 rpm and drop the clutch?

Guys thanks for al your help. I just did not find any posts about it.
 
read around the forum for common problems and things to avoid. i know if i had done this i would not have spent so much time fishing stupid stuff... and DON'T BUY A COLD AIR INTAKE! (i hydrolocked)

What did you do? Drive through a lake?

It's VERY hard to hydrolock a motor even with a CAI.

i second that... to be honest.. i had a n/a 1.8 i stuck the cai on it./... put a bowl of wather up to and submerged the filter no hydo lock just stall out.... wont tryi ti with my MSP but you should be ok.. Get AEM hydolok valve if you have a CAI and are worried

i agree with bold... but there is no braking required

yeah, braking is optional, depends how fast you want to slow down ... or if yo u're doing a bit of heel and toe.

i know. :) i wasn't calling you a dick. lol

i find that driving a turbo, you have to be alot more attentive of your input. not like an NA car, where you can just mash on the gas and go. this one, i really have to watch the revs in a corner or else i'll come out flat, waiting for the turbo to spool.
