im thinkin about boostin my b18c1 in my del sol but i hear it want work good because my compressions high. so should i boost it or not?

vtec4lyfe

please search there are many threads on HT that are about boosting specific engines

my car is on ten pounds same motor

you can boost it totally stock, but I wouldn't reccomend anything over 250-275whp(to stay reliable)

You can but be safe on boost. 10 psi would be the absolute limit. Also make sure you have a good tune.

10psi is variable on the turbo.

A "hp saftey number" is more efficient.

broketuner-Sol_Si said 250-275 - I don't know much about B's so I can't discredit/back this up, but you definitely want a hp # - not a psi #.

apparently you don't know much about anything! a psi # would be a way more effecient number than a hp#. how the hell do you expect him to get a HP# without a dyno? DORK!

It's completely variable on the turbo.

A psi number is fine for a generalization, but without knowing what turbo it is it's a useless number.

Depending on the turbo, some turbos at 10psi might be yielding a lot more HP than others. If put over the "safety" level jeopardizes the reliability of your motor.

So no, STARTING with a psi number w/o knowing what turbo is a horrible place to start. You start a HP number and work from there.

Don't believe me? Go post in the FI forum about it.

Hey guys,
i just need some clarification...
Isn't 10psi still 10psi?
The only difference i can see is how soon it can get to 10psi... is this the case?

Syndacate is right nub. Different turbos put out different amounts of power under the same amount of boost ie a big *** turbo can run a low psi for a number a small turbo would have to run higher amount of boost to get the same power to the wheels.

10psi on a small td04 greddy turbo= instant response and maybe 200whp

10psi on a gt35r= lag and well over 300whp

10 psi on some t88 or something real big like that= OMGWTF?!?!? whp

DO NOT listen to philosofy1...ask this same ? in the forced induction forum, all the experienced people will tell you whp is whp and that is what has the harder effect on your engine NOT psi. Only tards or noobs will tell you to a psi # when you don't even have a turbo picked out yet.

It's probaly closer to 300whp that a stock motor can support reliably, but I'd keep it around 250 to be safe.

this all makes no sense. 10 psi is 10 psi. why would the turbo matter?

u have a small turbo @ 10 psi, and u have a large turbo at 10 psi. why would they not flow the same amount of air? they are at the same output.

BlackBeastEK

they are different sizes

broketuner-Sol_Si

your right the preassure stays the same PSI wise but bigger turbos make more power than smaller ones at the same boost settings.


would you expect a turbo this size -&gt; . to make the same power at the same psi as one this sized -&gt; O

they push different volumes of air at the same psi due to their physical size difference.

The difference between different turbos with the same PSI is the CFM (cubic foot per minute) that the turbo will flow.

you should read before you post.

you always set goals/limits in hp. never psi values

10psi on a gt35r is gunna be a whole different story than a tiny t3

Being the truth

philosofy1 = owned.

Yeah Syndacate hit it on the money...I had a t3 .42/.48 and put a 57 trim t3/t4 and left the boost controller at 14lbs and all I can is WOW! Big difference at the same psi level.

are you serious....i want to know where you get your information so i can stab them in the heart..thats saying a turbo off a mr2 at 10 psi would flow the same as a turbo off a peterbuilt at 10psi
