I didn't know I would be pushing for this power level when I started or I would have used a rod with a higher hp rating. Does anyone have experience with these rods @ this hp level?
I have a 92 hatch, fully built H22 with a GT30, Blitz sbc (has progressive boost).
I typically run 13 psi (350whp) and sometimes bump it to 17 (435whp).
I am considering a GT35 to use lower boost levels for the same power and wondering about raising the higher boost level to 500 whp. Car is street driven only. I've had this setup for 2 yrs. and around 10K miles. Ran 19 psi (465whp) for 5-6K mi.

i'd think they would be ok, whats you're setup? just curious im a gt30R h22a owner as well 350whp at 13psi... Mustang dyno?

I have no experience with these rods, but there is no set whp breaking point, where if you pass it, they will break. Either way though, as long as the tune is good, I dont see a problem with them handling another 35whp.

non-VTEC

you spent a boat load of cash on the engine/turbo setup and you put in "econo" connecting rods......hmmmmm......well i guess they will work. if you look at the machining/forging of those rods they do look similar to eagle H beams which have been proven to take over 500whp on many setups.

the only reason crower underrates their "econo" rods is so it wont take away the sales from their "premium" forged rods. if they claimed the econo rods to handle the same power (or close) to the premium rods everyone would buy the cheaper rod and save 300 bucks. so they low ball the "power" to scare people away.

I'm curious. Why sleeve that motor for those power levels? Especially since it's a closed-deck block?

purpleh22

Stock sleeves are made of a material (FMR?)that is not very compatable with forged pistons. Mahle makes a Gold Series piston that is supposedly workable. They were new when I was building the engine and I didn't want to worry about how well they actually worked.
I also think that later H22 bolcks are open (97-98?) Mine is the earlier closed deck though.

stpacura

I have the same concern.
Right now I have a set of both crower and eagle h-beam rods, I'm going for a power range of 650 to 700, the thing is I don't know which ones to use.
I have ask around and the input ppl have given me is to go with the crowers because the eagle h-bean stretch at those type of number.

So from some of the replys I have read here it seems the crower is the way to go.
What do yo think?

purpleh22

I would think that if they are good billets, they would be stronger than Eagle forged rods. I had them magnafluxed anyway because the econobillets are made outside the US and I wanted to be sure they weren't flawed. Crower does all the final machining but I had it all double checked by a good race shop machinist.

purpleh22

Anyone using Crower Econo Billets @ 500+whp?

holy smokes, I got 366whp at 12psi on my china t3\t4!

As for the topic, rods on these setups seldom fail due to raw power, they actually fail due to rpm, so you may want to consider how high you are going to rev before worrying about it. If you are on a stock h series tranny, I wouldnt advise going over 7500 at any power level in which case the rods in my opinion will be just fine.

wabaki

i believe econos are equall to eagles. lots of people running hi hp on eagles good ol' china made rods

purpleh22

My setup is making increasing power @ 7500 and does not fall off until 8 k or so. Had the trans rebuilt before the engine and turbo work. In 2 years and 10K no probs. yet, but it's street driven only.
Why would the stock Prelude tranny make a difference?

oneludesol

H series trannies hate R's over 7500 trust me... they will handle all of the power you can throw at them, but be careful with the revs.

why do you need 500 hp in a FWD STREET DRIVEN vehicle?

oneludesol

because its nice to be faster from a roll than most liter bikes... Im the same way

purpleh22

Usually run it on low boost setting @ around 350whp. Occasionally run on higher boost for fun. Had quite a bit of experience with built cars and bikes. Although not as fast as some that I've owned, it's quick and a rush.

oneludesol

I get too addicted to the power, I stay at peak power all the time, i cannot turn anything down, thats why I overbuild things and tune well on pump gas hehe

purpleh22

Why do I need 500 hp for the street?
Think of it as a quest - you'll figure it out!

We live in a time when 'stock' bikes are turning 9 sec. 1/4s
'Stock' cars come from manufacturers with 400, 500, 650 and even 1000hp.
I'm just trying not to fall too far behind!

Ok. What about Crower econo billet vs. Eagle forged? Would the Econo-billets be stronger than a forged rod like the eagles? Is a billet rod typically stronger than a forged rod?

OUTKASTEG619

this is crower here.on this site to see whos a bullshitter.for the guy from toronto where are you getting your information from??you say crower does this and sais but you have no idea what your talking about.unless you to directly to us i would best say think before you speak

purpleh22

Just viewed a Crower add stating that their Econo billet rods are good for 650 flywheel hp. That would be over 550 whp.

streetracer6rpt

either will be fine. if u run the eagle rods just replace the rod bolts with arp bolts...

locash

It is readily apparent that Crower needs to hire someone that can spell and use proper punctuation.
