Question No Rev Limiter on the Getz CRDi????

I recently returned from a trip to Goa. My friend who owns a OHC Type 1 VTEC took the wheel after I finished my driving quota started off revving hard and I had my wary eye on the speedo and the RPM, and he was doing more than 5000 rpm on first second and third gears. The problem is the RPM shows a redline at ~ 4200/4500 rpm and he was going way over it touching 5500 rpm at times but there was no rev limiter in action. I am used to my Swift and I can feel the rev limiter coming into action close to ~6800 rpm and you can feel that the engine cannot take any further rev's, but there is a total absence of this on the Getz CRDi. I got my friend to control himself to less than 4000 rpm there on, but I checked again once I got back to Bangalore and I still found the car in the same position no REV LIMITER!!!!.

Any of you CRDi people out there faced the same situation or have you encountered the rev limiter coming on at the peak RPM??

I hope I dont end up damaging my engine...

Why do u want to cross the redline when u have all the power and torque @ <4000 RPM..??
Its a D I E S E L with VGT but still it ain't a VTEC.

KP I don't want to cross the redline, and I am aware that there is more than enough power n torque <4k rpm, I wanted to check if the rev limiter does exist or its missing on the Getz CRDi

Hi,

get your car checked! IMO it should have a revv limiter.

Cheers,
Shrey

Whether there's a Rev Limiter or not, I don't know. Haven't driven my CRDi like that yet.
But always advisable to stay at 4000rpm to avoid any damage to the engine. I cannot imagine taking my car to 5500rpm in 3rd gear! Even though its a good engine, it has its limits.
I hope your engine has run-in already.

I've driven a Verna CRDI. And I remember the power tapers down 500rpm prior to the redline.
Understandably, your friend seems to have hard revved it since he's used to the OHC VTEC.

About your problem,don't mull over it since its not affecting anything as long as you have a mental rev-limiter. Although, just ask the service guys at the next service . Just don't go along fixing what ain't broken.

Come to think of it, I haven't hit the limiter in my Jeep or the C220. The Jeep, well, understandable for such a basic oldschool engine. But the C revvs beyond 4500 rpm (easily)...a little more than you can feel the engine getting strained. I don't take it over, but the rare times that I have, it is the engine that has been stretched. No cutoff.

Agreed with kpzen : No point revving diesels too high, it's just a waste as you have left your torque behind.

I am curious to know if any others have hit revv-limiters in Indian diesels.

P.S. Hahaha, that sounds like a typical high-revving Vtec guy.

IMO the diesel dont hit limiters like petrol cars.. ding ding ding style,They simply go and stop at a point.

Beyond a point, I've actually felt like going backwards (especially on inclines) after i spun past the peak torque/power band, Besides, like kpzen said , there is nothing interesting beyond 4k anyway, and you would have noticed it, unless you were going flat out on level ground
