R33 non turbo performance

[DennisRB30]

Yeah, many people reckon that an auto VN would normaly beat a near stock 5 speed R31. Its probably true. The humble VN is (as much as I hate to say it) probably one of the fastest non performance cars you can get. Mine has no trouble winningfor some reason. Not every time, but the vast majority. I think a 15.9 backs it up though. Maybe its just my driving style and dodgy homestyle mods?

I don't belive in stop watch figures but somewhere in the high 7's is what I thought I got when I done it. A more reliable way might be if someone enters my 15.9 and trap speed of 138 km/h into a racing calculator, those calculators normal work well. On the day I went to willowbank all stockish V6 VN autos ran mid 16's and the best I saw a 5 speed ute run was a 16.2. (dispite the manual being quoted as doing a 15.7 which is pretty damn good for a dunger family car)

And as for the new commodore, (nelson voice) HA HA. (end nelson). What a dunger. MY brother said he went cruising in his mates supercharged VT V6 calais, and it got beaten by heaps of auto VNs. So I agree with the newer heavier slower rule for commodores. You would have to be pissed of to have bought one of these new commos. Does anyone know what the 400M times are for the new ones?

I forgot to mention..

My inlaws have a 91' VN Auto, Its now done 280,000km's, had a motor rebuilt at 230,000 and trans at 260,000.

That for some reason only runs 0-100 in a mid to high 8.

The inlaws other car a BMW 4banger 318is 5speed sits neck and neck with it.

I do think the motor had a bit of a rough rebuild though, it doesn't sound quite right and is as rough as hell.

hey.. What about the old TC 4speed Cortina's.. lol

A mate of mine bought one that had a 250 2v motor in it.

Apparently from factory they made 170hp (126kw).

He put a 350holley, extractors and 3" straight through exhaust and managed to run a 14.9.

Went pretty damn hard at the time.

It used to be slightly faster than my TE 250 4speed with holley, extractors, holley and mild cam.

I remember those days like they were yesterday..

lol I went through 6 4 speeds, and 2 auto's.

The auto's were a little sluggy but couldn't be beaten for street long unlimited length burnouts. lol

ahh the days when I didn't seem to worry about loosing my license.

there is quite a variety of fast and slow VN commodores though. i have a theory that the series I VN's are faster. basically because with the series II, they *fixed* the temporary cooling system slapped on the series I to accomodate for the FWD to RWD adaption. with the series I, the inlet and outlet are at either end of the engine, thus requiring a much longer hose to reach to the rear. with the series II the longer hose was eliminated by making both the inlet and outlet at the front of the engine. the problem with this is, that the cylinders run at slightly different temperatures. with the series I, logically its likely that you will have a more even temperature between all the cylinders creating more efficient and more powerful combustion. this is by no way proven or anything.. its just a theory. and my VN is one of the last series I (8/89).. and its a bog stock auto wagon with roof racks, electric everything so its about the heaviest VN you could get and it ran under 8 secs 0-100 :wassup: btw, over 100k's its nothing special. im sure it would be left behind by VS's (maybe close with a VT) and should be left by a VZ too.

oh and go the TC - TF 250's! they rule... 25+ years on they still cant make a base model falcadore go any harder... and i am also a witness to the fact nothing beats the burnouts those things can do!

[DennisRB30]

Well I have one that I use just for burnouts it a TE 250 with 4 speed, stock besides locked diff and extractors. It smokes it up in 4th with both wheels spinning on a burnout pad, I reckon that would be a tough ask even for a GTSt.

The series 2 VN had a inlet modification in the form of a ram tube in the plenum. This made the car idle better and created less "wheel spin for worried soccer mums of the line" That said my mate has a S1 VN without this tube and I still beat him every time I have raced him. It is actually a performance mod to remove this tube in a S2 VN.
