How much boost on a Gsr with forged internals to run 13 flats?

 

depends on: compression ratios, slick size, weight of car

on average i think a gsr at stock compression could run a 13.0 at 5-6psi on 22in slicks

At only 5-6psi of boost!?

 

I ran a 13.3 at 108MPH at 6-7psi on 22" slicks. Plenty of power, not enough driver.. ha.

 

Whoaaa.. I need slicks!!

 

the trap speed is definitely there for you to run 12's.... what are your 60 ft times like?

 

They were like 2.1 I am thinking. I am very gentle on the launch. I haven't broken anything in 2.5 years of being turbo!

Well I take that back. I broke one axle. I was coming out of a gas station and did a hard 1-2 shift with the steering wheel still not totally straight and broke one. Not catastrophic tho. Limped home and changed it.

 

how did you limp home on a broken axle? Even if you had a diff, that would put extreme amounts of load on the drivetrain. Scary stuff

 

i hear ya on that... but i got to say... the car will take alot more abuse than you think.... 22in slicks should net you in the 1.8-1.9 range on your 60fts... I was pretty skecthed on launching at 5500 too at first but once i figured its better to spin a little that have them bite real hard and wheel hop, it was all good... ive been turbo for 2.5 years as well, and to this date have never broke an axle (knock on wood)..... ha ha ha ive blown a motor tho

 

I think I just broke something in outer CV joint. Wasn't too bad. I only had to drive about 2 blocks from the gas station to my place.

 

While we're talking axels here, how much power do you think Honda axels are good for? I know my D16 axels are a bit skinnier than B-series but I wanna have a rough guesstamate as to how much these things can hold.

BTW I'm going w/ driveshaft shop axels soon so I won't have to rely on these

 

I don't think it depends as much on how MUCH power, bit more on how you LAY DOWN the power.

Make a mistake like I did punching it out of a gas station in first with the steering wheel still turned a little as you shift hard to 2nd lighting them up the whole way and your axles will be a little unhappy.

 

that is my goal....to run a13.0 on my sohc....w/stock internal's full interior....i hope i can do it.....oh well....give me a lil while lol i havnt even put the thing on yet.....anyone wanna loan me some money lol

u can surely run a 13 flat.....w/stock internals boostingl ike 9 psi on street tires for a gsr poc

 

go0d to 200 hp so far without issues. By spring I'll be hitting 225-230 hp on spray. 12.99 or spit a rod, ZEX baby!

 

its all relative, alot of transplanted motor will break axles easier because of the geometry change when banging gears, most people do not use the two torque mounts that b series have in Civics or whatever this adds to higher angular load and balnce shifts in the axles causing them to go out of round during acceleration leading to higher stress loads on cv/axle. dumping the clutch with min 320lbs of torque should kill stockers every time.
