How much horsepower can the stock rods handle

**Saddest** · 4-23-06, 12:14

i have an F2T how much horsepower the stock connecting rods can handle comfortably.?...

**n2o_matt** · 4-23-06, 17:35

prob more than the head can flow... But in all seriousness - i don't think i've ever heard of anyone breaking a rod.

You mean "How much torque can be made without the rods turning into S's". There have been members who've made 400+ fpt with the stock rods and one who's made that amount with 86mm FE rods (86-87 SOHC 8V 626)

so basically im cool with 350hp at the wheels as my goal.?

Who said that?

**Dyoel182** · 4-23-06, 19:00

Yes, but you wont get there with this engine sadly.

And why is that?

**Dyoel182** · 4-23-06, 19:09

Because if you have to ask you dont know enough to get there.

**rebel2k4** · 4-23-06, 19:13

I could slap down 300+ EASY in an f2t these days. Its a matter of tuning, boost, and knowledge. Period.

if you can get peak TQ rpm to >4500 rpm

yikes guys...don't put him down so much. atleast let him dream about 350whp.
dude, you're not getting there on stock fuel system, including injectors. once you do some research and learn about what can take you there, and then do it, then you will know. it takes tuning and knowlege, and a big ass turbo.
learn how to read compressor maps (talk to sixsick6), find out what will give you good power at lower rpm, meaning since you can't rev past 6 grand, what will give you good power before then. look into injectors, fuel control (fmu or something like that). It's not like I'm the master of this kinda stuff, but I've been around enough to know what you need. air, fuel, and spark...make sure you have enough of what you need. I think you should set a more reasonable goal, like 200whp at first

400hp, at the wheels....umm, probably not, but that doesn't mean it can't be done. 300 whp, sure you can, but be aware of what your doing...
turbo sizing, what you intend to do with it, what your budget it....there's all kinds of factors.....
Much like any other engine. Biggest problem is, our engine is a single cam, and the head is poor flowing, and like everyone will tell you, cannot create the "revs" like many other (twin cam) engines can. Our stroke is too long to make those rev's and a stroker can't be done, as far as I know.....
So you are limited.
Best thing to do, is, sit down, and think of exactly what you want to do. Putting a monster turbo on, and hopeingh for some big #'s, will only give you a destroyed engine, and money lost, if other areas arn't taken care of first.

BTW: Should we not put up a sticky somewhere on this, so all the new people don't have to ask the same stuff, over and over again..... I don't care, just people can put a stop to other people who don't know any better, really quick. This way theres less pissed off people, and less newbe questions.
I know this stuff is out there, but like always nobody wants to use the search button!

Depressing? Thats what I think I look like looking at my reflection!

hey well thanks a lot for the info there guys.
i just used 350Hp as an example tough my real goal is 300Whp. i just wanted to know weather my stock rods can take this kdina torture.
i presume @ 300Whp i should b ein the 12 second bracket am i right.?.
my aim is a 13 second car honestly.. but i like to aim higher that way IF i fall short im still happy.
im upgrading mostly everything on the engine. as far as rebuilding, and after market components, ignition etc.
i was doing some research on some stuff thru some searches on the forum only things i dont understand or cant find ill ask i hope i dont seem clueless to some of you but i am new to this. and i love my F2T its a sweet engine .
again much thanks..

but i am safe with my rods right for my goal that is.?. im goin forge pistons by the way. ..

also what type of aftermarket cylinder head gasket do u guys use , because all i seem to be getting are copper ones.

**chino9656** · 4-23-06, 23:48

I think your rods will be just fine. I chose to use reconditioned stock rods on my rebuild, because I'd rather use rods that have been proven for 16 years. new forged rods would be nice, but i don't think it's necessary...like they said above, I've never heard of someone f-ing up an f2 rod.
honestly, you need to do some more reasearch on what it's gonna take, though. especially what are you planning to do about your fuel system
