i was thinking of doing a setup similar to this a-beam rods stock pistons hd valve springs stock head thinner head gasket and about 50-60 shot of smack would it work ok would stock pistons hold up any feedback would be great o by the way j your bike is set really nice i like that look

i have a 07 gsxr 1000 std bore stock head & cams with 1mm shorter rods with custom cp pistons with wrist pin moved down 40 ths case & head studs with a 60ths head gasket made 165hp on motor and c-23 had 4-31 jets drilled in head made 310hp with spray im 185 in shorts bike ran 5.43 @ 142mph in 1/8th 8.30@176 in 1/4.the shot was dry also i ran in real street last year.

176 MPH, you got a 7 sec bike man.

the 1/8 et and 1/4 et was not on the same run that was my best times i ran a 5.53@137 1/8 on my 8.30@176 pass.i dought 7 secs but some 8.0s would be nice.

[brown racing]

how much head work can you do to a STD bore block that will make power and what is the biggest cams you can run?

to me i dont think bigger cams or head work will make much or any difference.spraying that much is hard on the head if you dont have it set just right i have a shop full of eat up heads not worth all the money for bigger cams or porting just my opionion.

I forgot bikes backhalf better than cars IE the high mph.

standard bore, and if you could wedge a slightly longer rod in it and make it around 11:1 compression...id try a 2 stage 180 shot on it. but id also have the windage holes welded

why would you have the windage holes welded. I just told you I sprayed 150-180 all year with no issues? And no rod issues.

As for cams a good set-up on stock bore is the stock intake cam on the 05-06 and an intake cam from an 03-04 1000 on the exhaust side.

On the head a good clean up would work well and some port matching but one you spray so much the nitrous is just eating the head. But good fuel and tuning is the key here.

i didnt read all the post lol..

i would do just for peace of mine...and if i wanted to go bigger, itd be done... one of these built right could prolly hold 230 extra in now...if the tune is on, and you use nice smooth nitrous ramps...would be a quarter mile bike. youd be hard pressed to get that much in, in the 1/8

whats the fastest anyone has ever been in the 1/8 with a std bore nitrous motor?

i would answer that but if i told you, you wouldnt believe me.. but there are stock motors out going as fast and faster as some built motors...
also you have to understand alot of it is the setup. very low 60s.....

along with your tune, your set up is key...

There are too many variables that would decide how a stock motor std bore on spray can go. I'll bet you some have been faster than 5.60's. Hell I've seen 5.68 on stock motor with my 135 lb. friend at 63in. with brock smeg and pc3 and airshift in cold december weather on mr11. Im setting my bike up this year on a grudge chassis to shave weight and got a penske. And I'll tell you I know I'll do a lot better than 5.60's. all stock everything in the motor
