Sandrail Plans

What is redline on a 1800cc vw engine in a sandrail?

Anyone know what redline is on an 1800cc VW engine. My Sandrail has this engine in it, It has been bored out a bit but not sure exact numbers off top of head. There is no tac on my buggy, So im putting one on, But curious as to what you can take these engines to before hitting redline, planning a trip to desert in the summer and want to make sure I set redline on this tac at the right spot, So I dont blow something up to quick by running it to hard

i wouldnt go set it any higher than 4600. trust me
