and thank you all, for the numbers..

Here is another fresh test number. I just did this not 10 minutes ago.

Car fully warmed up and up to operating temperatures, 2nd gear pull with the GPS on for my speed. I was able to hit 81km/h and it still had more.. but she does have just over 310k kms on it.. so i didn't want to push it.

81km/h with my tire combo of 185/60/14 nets me 5614 rpm's at that speed in 2nd gear.

Kev your AUG trans has the same 2nd gear but the lower final.. so to reach the same rpm you would need to do 85 km/h or 53mph in 2nd gear. We both have modified governors so its achievable for sure.. no way your tellin me you car has issues doing over 5200 rpms in gear.. it should be able to spin up way higher in neutral.

my car will go almost 60mph in 2nd gear. i need to figure out where my in-accuracies are coming from..

AGS with 3.67 final. 50mph with Giles pump was very attainable. I usually shifted as it didn't make power after that, but to find that out I think I did spin it to 56mph or so. Mine wouldn't do 60mph in 2nd no matter what. Giles told me the gov is pretty much disabled on my pump...but I think he does it with a little more sophisticated stuff than 2 hex nuts like I did on my N/A pump.

What are your two's tire sizes? Plug that info in this this and tell me what rpm you had that at in 2nd gear.

ok, i should have said, my car will go a little more than 55mph in 2nd..

my engine spins 5750 revs, in neutral, foot to floor (5 psi boost too!)

i have a disabled governor in my pump. its shimmed solid. so the rollers gotta be skipping..

i have 185/60/14s also, 3.67 final drive, AUG trans. GOD ITS FUN WITH CLOSE GEARS.

every time you shift, it wants to burn the tires.. sometimes its HARD to get the car to hook up in 1st/2nd/3rd gear..

185-60-r14
5788 rpm

Safe to assume rollers start skipping just after 5800 on a stock (not including governor) pump then?

i would think soo..

What RPM do valves float at? Maybe they could be a limiting factor before the IP

[RadoTD]

I don't know about 1.6's, but my 1.9 has the same dual valve springs as the gassers which I know people run 7000rpm on stock valvetrain, so that shouldn't be limiting

[8v-of-fury]

stock 1.6/1.7 should easily be able to do 7000 stock as Rado says..

I know I had my 1.7 EN Gas up to and above its redline of 64-6500, with using a wiper relay instead of a fuel pump one lol

I think the 1.8 8v gassers rev limit to 6500-7200 (don't quote that ) depending on if it's CIS, CIS-E or digifant. The 1.6D has dual valve springs so I would think the valves would be fine at the same rpm.

~6250 rpms is the rev limit for LOTS of 1.8 gassers.

From the bentley.
Engine RPM limit
Code HT:               6200-6400
Code RD:               6570-6630
Code PL 16V:         7200-7300
Codes RV and PF:   6500
Code 9A 2.0L 16V: 6800

I've only dealt with 1.8 8V's and the redline on them was 6250 so you were partway right .

thats why i said LOTS of 1.8s had a 6250 rev limit. most of what ive owned were HT's and GX's (CIS-E & CIS-Lambda)

ive never seen a digifant car that would actually turn 6500 either..

[8v-of-fury]

Girlfriends got a 90 RV motor behind an 010 3spd. 2nd gear will haul its ass up passed redline (6500) till about 6800.. Thats when i push the stick to 3rd
