ive been thinking for the past couple days about even going supercharged and i was wondering...in theory what could the 2.4l le5 motor(stock) accomplish with a harrop blower?

Jackalope

It all depends on what you define "stock" as. Also how much boost?

But I think its only good for 300 and something before it blows its rods.

brickerenator

Only one way to find out.....


You might try looking at the Solstice 2.4 builds to see what has been done

depends on how much boost u run. i know the 2.4 on the stock blower off the 2.0 would make over 200 whp on just 8 psi, thats everything stock.

a stock 2.4 with a harrop on it would go boom. wouldn't expect much of anything.

wow the only person that posted something worthwhile lol

how much would it take on the harrop no idea..

it makes about 240 whp on 8-10 psi with the m62...

and then there are solstices running stock engine at well above 300 whp...

i think it would be very interesting to drop the tvs into a 2.4 ... i think it would produce some nice numbers

mike25

just an idea..not sure of anything technical

celicacobalt

i think the 2.4 with a good tune should be able to put down 400whp on stock motor

mike25

your refering to the harrop?

brickerenator

haha
that would be a craaaaazy tune if he wasn't

in general.. i think the harrop will be a bit less though do to parasitic loss but it should still pump out some numbers

brickerenator

as compared to....the M62?

mike25

how bout this....close to or right at 300hp reliably on a stock motor...and then close to 400 built with a better tune...achievable?

i was talking about gettin 400 whp on a turbo being possible but harrop/ m62 will result in less because of parasitic loss.. m62 even more because of heatsoak..

sorry i didn't really explain..

also i'm not sure how our fuel system is .. if it'll **** the bed on a roots style sc at high boost and starving cyl 4.. like on the lsj's the only 400 hp 2.4's i've seen / heard of are turboed

Dunkinuts

in all honesty I think the LE5 will handle nitrous better then boost.

elecblue06

iTrader: (1)

actually quite the opposite depending on the form of boost.. nitrous is a sudden shock to the system.. gm popped the 2.4 at like 250-300 hp using nitrous.. and popped the lsj at about 350 using nitrous ..

is a sudden stress on the engine.. which is mor elike a roots SC something that eases into it more like a centri SC or a turbo will be easier on the engine

true you could do that but then you'll have a really expensive setup

mike25

point is this thread wasnt made conscerning nitrous....

tsunam1

I HAVE NO IDEA WHAT I AM TALKING ABOUT....BUT...the TVS just sounds like a more expensive option when you could go m62 and use a smaller pulley instead of the stocker. More air is more air, has anyone with a sc 2.4 tried that, or is that totally ridiculous?

pjk91

340whp on the big pulley they send with it. 380+ with the small pulley.

mike25

how would that do on a stock motor? bad or ok if tuned right?

also take for instance i go and put in forged rods/pistons, possibly the same compression, or a BIT lower(9.5 at most)...how would that do? alot more reliable?

Not happening.

To the op, i would be a little more concerned with the trans as i know the s/c 2.4 guys were having a couple problems keeping them together.

mike25

hhmm now that you say something i seem to remember that....i guess in short it just really isnt possible to run a supercharger to extensive...thanks for the info...back to turbo i guess..lol

How is the m62 for fitment on the 2.4l? Mainly clearance of the fuel rail.
