turbo question???

[BadAzzRS]

Heat is a main reason of power loss with a turbo, or an incorrect setup, untuned setup. but when it comes down to it, its all about too much heat.

and for turbo your HP loss will mainly be the CAM, cam cam cam cam cam. if you have stock cam you'll have more loss, were a turbo cam shut the exuast vaule b/f it can affect the in coming air and piston, and keeps the exaust PSI weres it expose to be, spinnning the turbo !!!

With a turbo you have to burn more fuel to make each hp than any thing else.
N/A = about .5 lb/hr of fuel per hp
SC = about .55 lb/hr of fulr per hp
Turbo = about .6 lb/hr of fuel per hp
Turbo RX7 = .7 lb/hr of fuel per hp
Brake specific hp consumption
Of power adders SC and turbo the SC should need less HP to drive it.
So there is now why turbo gives free hp.
You here import guys (the ricers mainly) say that turbos are more efficient and that its free hp.
Just because you can see the belt driving the SC you know it needs power to be driven, turbos are a litte different you cant see what's in side there going on if your just standing there looking at it.
They just say it as a general term, they don't say whats moer efficient but that just that they are.
I here it over here all the time ( you state side people have no idea).
If they stick around to here me repeat my self very very slowly after about the 4th time they start to catch on.
The only free hp is nitrous and nitrous is about $10 a pound over here and you need a licence to buy any compressed gas (this place sucks).

SC use up to 200 HP to drive them depends on set up

turbos use 20-50 depending on set up but turbo have the low end lag so.......

cam should be based ont he setup ur using. yes, u want the exhaust out in the manifold where it can spool the turbo, but sometimes u can get away w/ a more NA looking cam for low-backpressure turbo applications.

here's 2 examples:

224/220, .525/.530, 116 lsa

224/220, .525/.530, 114 lsa.

The 1st cam would be better with a smaller sized turbo, since there's less overlap, meaning less chance of reversion at lower rpm, especially since smaller turbo's tend to spool quicker neways.

the 2nd cam would be for a larger sized turbo with more lag and a higher spool rpm. it will take advantage of higher rpm flow characteristics and decreased backpressure. it'll make a ton more hp than the other one will, especially since hp is rpm dependent, and the turbo and cam are both designed for higher rpm's.

I'd also like 2 say that the duration and lift I picked were assuming a slightly overbore 3.8, meaning .020 over, and a set of ported heads.

my cam i picked for my car is

224/215 .535/.534, 116 LSA @ 110 intake center line
