HP build level

(1/1)

wideopen231:
Reading thru some old post and noticed a lot had a HP rating on various pieces. WOndering how most approach this.

You can build a 700 hp piece using stuff rated for say 800 Hp,but have choices of higher rated piece.

Cranks are one example. Transmission p[arts is big example.

Me like to buy most over rated part I can afford and most of time stretch the afford if it will destroy other parts or my car.

My motor is kind of example. Its old parts(almost new stuff) that was designed for fuel cars 20 years ago. As strong as TF stuff now no.Stronger than most 1000 hp motors by a long shot. I almost feel guilty using it such low power out put. Only doing so because I could afford it.Two short blocks sitting in corner aging is pretty cheap.Plus old technology brings 20 cent on dollar and not buying much of a crank for 600 bucks. LOL

I believe in overbuild, underuse.

i have a billet crank in a 1000hp engine.  I know it won't be a failure point. 
I have GRP rods in a 1000HP engine. yup, i could run Eagle, but i'd be pushing the envelope.

I completely believe in the "pay now or pay later - but you're gonna pay" motto
