Just finished racing at the GLC last weekend, The motor performed flawlessly
Super fast campletely stock shelf bought motor. This motor guided me to a 6th place A-Main.....I have already put about two gallons thru it and it is still very tight....incredible.

They were also clocking cars down the straight at one time and I was told this motor pushed my car to 62.7 mph second fastest among tourings....and this motor is stock.

its good eh

Hi Robert, I noticed you ran the same gearing as I did on the STI at the GLC. What engine temps were you getting? Mine was reading at around the 260F mark.

Oh. One more thing. How did you manage to make 5 minutes? I always fell at least a lap short of finishing a qualifier. It was quite frustrating. I was running 25% Tornado and tried with and without an extra shim.

I used 7 plug .....head clearance set 20 tousandths...temps got to around 250-260......you basically ran exactly what I ran...unless your head clearance was off...also remeber the car has alot to do with fuel mileage...the smoother your drivetrain is the faster you will go and the more mileage you will get ;)
Dave whats your last name....so we can formally meet... :D
Hope this helps

My name is David Ribeiro. I believe you spoke to one of my fellow Canadian racers up on the driver's stand at the beginning of the B Main. (Santino Nemi)

Wally, I ran the Skyline VR12+. I tried the Novarossi 2630 but the motor lost too much bottom end for my liking. But I'm not worried about Fastcats, I'll make runtime there easily. :D

The key to improve the mileage is a correct clutch adjustment and, sorry if this sounds weird, a good gearing. On the case of Sirios, the most shocking thing was my fuel mileage improved if I shortened my gearing going 1 tooth down on the pinions (1st and 2nd gear).

Try with shorter gear ratios. Many times too.. fuel mileage is a 'Digital' problem, so watch out your finger mashing the throttle too.

I was thinking of trying out an INS box filter. I remember Josh Cyrul was using one last year on his Evo2 in order to make run time.

Bull wuz up mon.....hope all is well down there ....give all the fellas a shout out :cool: :cool: Bull you gotta make sure your clutch is set properly, try running a seven plug, also you might want to try and run 20 tousandths clearance, also lowering your nitro content will give you more run time....I ran 25 percent at the Glc and the motor was very fast and I made time....also bull remeber how free my car was when you saw it that also helps with getting run time....hope this all helps..

the vr12 should work and ya clutch and gearing are key,im gona run 16% in hamtowns can am race then 25 at fastcats,i was told that the gearing is way diff than nova based motors,you gota play with it,oh and the nova pipe dosent work good but the sirio is the best just cant fined one yet.

Not true nova rossi 2630 works great with the Sirio evo3 I used it at the Glc
tons of bottom.....and car was clocked second fastest down straight.....this pipe also lowers temp on motor.... :nod: :nod: since it lowers temp...this allows you to lean it a little more getting that valuable run time.. ;)
