No worries Rex. What's an inch between friends Guess it sorta depends just how close you really are

i thought i read in here somewhere that for the turbo head you can run a O'Donnell 77t or a 97t....but the last 3 or so pages, people were saying only os plugs...so has something been proven that 77t and 97t cant be used now?
thanks

you can run the O'Donnell plugs in the turbo head. If your not running the turbo head you need short OS style plugs.

I've had good luck with the Odonnell 97t, I've been meaning to try the 77t but haven't yet.

Rex

ok thanks guys....

Without taking the LSN out of the carb... can you tell if it is the long or short needle?

you can tell if you remove your air filter assembly and look down the carb with the carb slide pulled to full throttle.

if it's the long needle you'll see that the needle is still almost completely across the opening. if it's the short needle it with be almost completely unseen.


hope that helps

Adrian

it's only the standard plugs that you need to run the short body OS style plugs otherwise they screw to far into the combustion camber.

you can run any turbo plug you want with the turbo button nova, RB, OS, O'donnel etc etc and long or short body with out a problem it's just that some work better than others.

also GO have now started making their own turbo plugs so you should be seeing them on the market soon and maybe a bit cheeper than most other brands too

Hi ya Adrian. How goes it ? Long time no see.
You racing Hamilton next week ? I believe they have a new track laid out.

I ran the turbo .25 all last season. It does everything a turbo head should do like a little more RPM, better idle, etc. but it did appear it made the tuning a little more finicky than the .21s.

Not sure if they are going to release it or not but its worth the upgrade and im happy i only have to carry P3s to the track.

Raced my 7 port last weekend and did well with it
I have it as grizz advised .75 HSN and 2-2.5 LSN
But I haved noticed that it is slow to respond at the start of the throttle and then it just screams after 1/6 throttle
Am I too rich or too lean
20 min mains and had fueled only 2x and still have 1/3 a tank after 7mins
I love this engine it is just so difficult to be consistent with it when the climate changes in the same raceday
thanks

doing the pinch test has helped me get the low end set very good on my go engines.

The 7 port should be smooth throughout the powerpand.

I've always been trying to get a smooth powerpand...

(this is my race report from last weekend, and as i race for GO Engines, will duplicate it here)

Well guys,

I just came from the first stage of the Chilean Nationals 2009. A 2 day event on a very high temperature ambient (+- 97°F) with great drivers and awesome track.

This race was the first for me with the new R2 chassis, i received the RTR version couple weeks ago and i decided to put it on test on this race AS IS (or at least wanting to change just small things). I didnt had the time to check every screw on the car, just installed my servos, engine, pipe, receiver and battery, changed the stock diff oil and shock oil and went to race.

I used the stock shocks for the first 2 x 10 minutes qualifies without any problem and then noted a very small leak on one of the shocks mainly due to the shock cap being unscrew (i think, due to high heat). So, i decided to go with the old Super Big Bore Jammin shock i was using on the old chassis.

It was a great experience to put this chassis on test going stock but going calm to know the chassis better, didnt put me on the A-Main, i had to race B-Main starting on 1st place.

B-Main was a 20 minutes race, i did a very good start and started to gain a little gap from the pack ... at minute 5 or something, i noted my steering went slower and 1 lap after i had no steering at all !!, marshals throwed my car on the pit area and my pitman discovered that the servo arm screw was off, he installed a new one (always have one on the pit area lol) and went back to the race, on 7th position. After a lot of fighting and my pitman yelling me to calm down a little, at the minute 19th i got the lead, just one minute to go and A-Main with Matrix R2 RTR .... HERE I AM !!!

A-Main was a 40 minutes high heat race, i did a more or less good start and took 2nd position ... by minute 4 or so i lost a position, being on 3rd but with 4th very very close to me. My fuel strategy was fueling every 8 minutes as my engine was giving me almost 09 minutes and 15 seconds. BANG !!! my engine stops just a curve from the main straight and pit area ... my pitman forgot to yelling at me and i had a flameout (great friend but first time asking him to pit me) and went back to race on 6th position ... i started to climb very slow on positions, did my next fuel stop without problems and got 4th position but almost a lap after the 3rd place. After a lot of fighting for the last minutes of racing i knew i had to do just one more fuel stop and the 3rd place 2 more and he had a difference of 1/2 lap from me, he enters to fuel up and when he go out of pits i was just 1 car difference in front of him, he is a very good driver (made the TQ of the event) and the pressure was all over me, i knew that i had to maintain the position and create some gap at least to fuel up and go out fast, after a couple mistakes from him a had a good gap, at least long enough to refuel and try to go out of pits in front of him, i was 3 curves before pit area and BAAAANGGG ... new flameout ... DAMN !!!, dry again !!!, the other guy entered to refuel while i was out of race so i was 1+ full lap behind now

So, even when i did my best over the last 5 minutes of racing, i was unable to close the gap and ended in 4th place.

I went down the driver stand yelling to my pitman about how he left me dry 2 times !!! and he was kinda overwelmed by the situation and just laughed and said "calm down Pato !!, just 2 times man not bad for our first time together !!!" lol !!!

Anyway, it was a GREAT weekend, a lot of great racing action and i ended more than happy with my equipment, my GO Engines 7 ports worked flawlessly, my VP PRO Tyres worked AWESOME and the chassis was a great refresh of agility, low weight and performance, im more than happy with the new R2 platform and i CANT WAIT to put my hands on the PRO version.

Well, hope to improve on my driving with this chassis, so far on that same track i raced on weekend, i improved my lap times on almost 2 seconds, my average time always with old chassis were on the 42 seconds field, and on this race i did consistant 40's during the weekend, with one high 39 and high 37 !!! (low 37 its lap record).

cya guys !!

Hmmm... pretty nice bumps you have there. Must be due to the climate or something
