os .18 tz
 

Sunday I had a chance to see this engine for the first time. From what I am told, the engine was just broken last week. It was pretty much tight form what I could see. My tc3 went down,(damn 1-way) but I was able to use his fw-05rr with a rody .15 in it. He used his g4 with the os.18 tz in it. Let me start by saying his rody was always real fast and he could never control it well. We ran on an 1/8 size track. We would punch at the same time, and WOW the OS did seem to have more topend and was at least as fast bottom to mid range. For under $200, I think I found an answer for the 1/8s that I love to play with. Hell, I know its not legal and oh I love my ps12, but when playing with the 1/8s, this could be the ticket. The only thing is, I am not sure on the gearing of the 2 cars, but I an sure he had them both beared up.

I think if you can get enough guys to buy this engine you can create a new class of racing(Super Outlaw).:D

Was the .15 a small or big block?

I assume the .15 was a small block, didn't really check. I will find but it may be on the weekend if the weather is ok. If not next week.

I would say that Rody 15 should be a small block. Now a day, the big blcok 15 is allmost OVER.....the old big block (even EVO4 MS by Nova Mega or Rody X15) are no match with now a day small block 15 like Max 15 or JP Mod Rossi 15.............

Yes, for under $200, the 18TZ is definitely FUN and worth to play around........but keep in mind, my 18TZ only lasted my 4 minutes, and you will have to find a whole new setup to beef up the rear traction of your ride with the TZ due to monster low/mid range speed........

My ntc3 cannot handle 18TZ nicely.........barely controlllable at the infields.

what happened that your 18TZ only lasted 4 minutes?

Try put your car on the track and do a full 5 minutes racing.....my 18TZ will only last me 4 minutes +/-...........never 5 minutes.

It is still too cold outside to do more testing........but my only option is leaning the high end a little bit more to gain milage, but then, i have to keep an eye on the temperature.

Bigger engines use more fuel, that is a common law............

75cc tank designed for 2.1cc small block 12 engines.

18TZ is close to 3.0cc..........that explain the 4 minutes run time.

LOL i thought you meant it LASTED 4 minutes, not as in runtime...nevermind.

You can get more time out of this engine, I run my .18TZ at around 240-260 deg. Your trigger finger is alittler heavy to, you really have to finess this engine around the track, you will get faster when you get used to the power. Also what plug your running? Also gearing will affect your run time.

I also might try a 1/8 scale fuel filter this will hold extra fuel in the line. Also add more fuel tubbing.

Yeah, I totally agreed what you said, and I do have everything you mentioned, my NTC3 was illegal at the beginning (78cc I think), then I have the Inferno fuel filter bottle, 2" long fuel line.....still, I can only do around 4 minutes +/- at a 300 x 350 track over in Hong Kong, racing against 1/8th like 950R and Evolva...

Speed is definitely not a problem at all, run time is the problem....and now, all I can do is wait until MAY and get back to TINLEY PARK for some fun tunning....

P.S...no matter how I tune it or set it, it is a fun engine to run around, never will be legal for any racing.

Oh, sorry about my not so good ENGLISH writing....yes, I meant the RUN TIME before fueling, I don't think I can ruin a solid engine like the 18TZ in only 4 minutes....

Will this engine work perfectly for a 235mm onroad car?

I will also be at Tinley Park this year for alot of testing of the new .12TZ and .18TZ engines. If you have any questions about OS engines come and see me I will be the guy with the OS Tee shirt on.

Ray

the NTC3 comes with a fuel tank insert for ROAR legal tank capacity:)

I do not have problem with 18TZ, just not so good on 200mm TC and a little bit short on 75cc tank....but on my outlaw 835, that should be a perfect fit.

See ya at Tinley in 2 weeks.............are you the same RAY that used to work at Al's over at Elmhurst?

You said it was a FW05RR and G4

The FW05RR doesnt have the best top end without gearing it right these have to be taken into account. The FW05RR is made for small - med tracks.

Yes...but for club racing, hardly you can find anyone will use it.....again, club racing does not do a lot of those after race inspection....if they do, they have to race till MONDAY.

I think it is perfect on 235 like 835 Impact Neo Advance..........However, I think it is only limited to SERPENT 235mm only cause Serpent does have a special small block engine mount designed for Impact and 835. item # 808381

The 18TZ is on my Impulse Pro with VDS conversion..........so, I expect another "overpowering"effect on the 200mm chassis, but I hope the GTP rear bridge and the Lola VDS body will generate enough downforce to keep the car down on the road, but I cannot tell untill I get to Tinley and run it.....

My other plan is running it on the 235mm Impact........I still believe that is the perfect chassis for the 18TZ...and I would not surprise to see that engine will run better then other big block 15 engine on the same car.....at least, I have the modded EVO4 7 ports Michael Salven engine to compare.
