89pathy3L Posted July 4, 2009 Share Posted July 4, 2009 Hey i know this might be a simple or noob question but what is the redline for a 88 vg30i? I usually shift mine around 3 grand but have done it at 4 before. also wanted to know if you have had yours running at 3000 or 3100 at 70 or if mine is high with these numbers Link to comment Share on other sites More sharing options...
Kingman Posted July 4, 2009 Share Posted July 4, 2009 (edited) Perfectly normal. Redline is at 6500 RPM abouts for this engine, or I believe that's where it's electronically limited to. At 4k I am doing 67 mph, but I only have 3 speeds and it's an automatic. By "I usually shift mine around..." it sounds like you're talking about a manual transmission?

Kingman Posted July 4, 2009 Share Posted July 4, 2009 Torque range is around 3000-4500 RPM if I remember correctly. That's where mine pulls the hardest. Link to comment Share on other sites More sharing options...

There will be a plate there and the last line will say HG43 Or HG46. This is your gearing, 4.3x or 4.6x. Tell us that and the size tires you are running and I'll tell you if the rpm @ 70 is too high. I'm going to guess that you have the 4.6 and 235/75/15 or 31" tires... B Link to comment Share on other sites More sharing options...
94extreme Posted July 4, 2009 Share Posted July 4, 2009 the redline is marked on the dash tachometer. some say their truck cuts out at that point; neither of mine ever did.. Link to comment Share on other sites More sharing options...
89pathy3L Posted July 12, 2009 Author Share Posted July 12, 2009 the redline is marked on the dash tachometer. some say their truck cuts out at that point; neither of mine ever did.. Yeah well I know sometimes it is right as far as what is marked but I also know sometimes those stock tachs can be misleading. I am running 31X10.50's and have stock gears all around. It makes an extra noise around 4 grand too... know anything about that? like a tick or similar to vtec when the timing changes... Link to comment Share on other sites More sharing options...
Precise1 Posted July 12, 2009 Share Posted July 12, 2009 Ok, but I was curious as to which ratio of the two available in NA you had, and yes, the VTEC kicks in @ 4k rpm. Is it pinging? Predetonation under load like when accelerating, passing or up hill? B Link to comment Share on other sites More sharing options...
94extreme Posted July 12, 2009 Share Posted July 12, 2009 btw. my truck runs around 3500+ when 70/75mph.. i do have the stick trans. i think the 89 with auto ran about 3000 Link to comment Share on other sites More sharing options...
beastpath Posted July 12, 2009 Share Posted July 12, 2009 my 91 is about 3000 at 70-75 too. Link to comment Share on other sites More sharing options...
89pathy3L Posted July 18, 2009 Author Share Posted July 18, 2009 ok, we're good. thanks guys. oh yeah, with 93 in the tank this time it runs a lot better and doesn't make the extra noise around 4k now. it's gone so it must have been pre-detonating right?
