No motor or car could touch my car's speed on the end field or the back straight... Ask anyone at the track... Your motor is nice and anyone looking for a nice piece of Art in a nitro motor should give Top Gun's motor a look... My TZ 3P is bone stock... Untouched and unmoded... Nothing special... Just an P7 plug, 30% nitro and the
Mielke pipe... Now let me say this... Is the TZ the fastest motor on the planet... lol NO... But when broken in correctly, tuned correctly and matched with the right tuned pipe, it can scream and hold it's own with any motor on the market... Mine is just plan fast... I've seen others that weren't as fast... Different car, different setup and so on...
I'll see you at CP Saturday TopGun and have a great week... You work to hard... Like me...

Hi Alan.
Yes, we are friends and I am not regreting it.
I never sad yout TZ is slow, what I sad it is that I mesure 34 0000 RPM.
I still think Novarossi and Sirio faster engines even out of the box. I saw Ron Atomic running his TZ at O'Donnell and it was really fast. He TQ in Las Vegas on stock TZ. But still I think that Novas and Sirios are faster.
About RPM-not neccessary more RPM is better. Some engines has power curve when if you bring it to 43000 RPM you gear ratio and tires roll out will be really small and speed will be slower and in the same time some motors can turn really "heavy" gearing and bring ammezing speed at 39000 RPM.
BTW, it is much safer to run on top of curve then on down hill-small deaccelaration for any reason will bring motor RPM instantly down and it will not recover till end of straight.
About stock or modded-this is really big question, yours TZ is stock and it is really fast, but why do you think stock can't be made right on factory fast?
The things like cuts on sleeve and other dremeling don't give anything not in performance not in anywhere. You know I don't cut my sleeves and recomend everybody to don't do it. Timng of events make difference, port configuration make difference, passing channel in cranck make huge difference, turbo scoop not really, combination of expantion rates on P/L make huge difference. TZ motor initialy done very good and it doesn't need to make a lot of changes, only central hole needs to be rebore from 7 mm to let's say 8 mm and motor will be really really fast. So modding and non modding it is more in our heads. You know there is some motors which you can mode very seriously, everything can be brought to specs, but still they are not fast at all, whatever you do-they are slow, other motors out of the box very fast and not required to do anything. It is mostly haw we use it, how we efficient, how we can use all power from motor on the track.
See you Saturday on CP. I will still continue collect data by my new software. Very interesting numbers poping up.
