Ok i have a 1994 honda civic del sol with a b16 block stock internals and a gsr head with ITR internals in the head and i was needing to know what is the compression ratio of this motor and i am planning to boost it. How many psi of boost will this motor handle safely with out messing up on me!!!!!!

 

well you have stock block so 8-10psi wud be safe,depends on turbo size as well

 

theres a site where you list your setup and gives you the compression but forgot the site if anyone knows it, put a link

LMAO. PSI does not mean shi<U></U>t when dealing with how much an engine can handle.

You have to go by HP

 

is hating on other people all you know??? i no but psi matters too, go ahead and boost 15psi on stock block and tell me what happens, then come talk crap

PSI does not ******* matter.

Take the 14b off a stock TSI talon. It will boost to 14 PSI in your car, and MAYBE have you hit 170 WHP.

You need to do some more research before you post anything else

this dohcgarage dude is garbage.....take what he says for a grain of salt

 

ya all you do is talk garbage you never help on any thread but you do post CRAP,man ur married and older but yet, very inmature

 

and why the hell you talking about talons?? its freakin HONDA-TECH!!! man i beat those pos all the time

All cars work off the same concept, no?

I was trying to think about the smallest turbo, and show you how PSI does not matter.

You are wrong. PSI does not matter. Compressor maps are what matters. Read up before you write anything esle.

 

so ur saying if i boost 15psi in a stock b16 with a t3/t4 turbo it wont blow??

 

Allright, I hold a degree in chemical engineering, but have not installed a turbo on a car. When you say compressor map I think of pressure vs. flowrate. With a given pressure and a fixed downstream flow resistance, including temperature adjustments, the flowrate (choose mass or standard volumetric) should be a function of only this flow resistance. The complication arises as to where you measure the pressure: at the compressor, before the throttle plate, or inside on the intake manifold.

So, where is this pressure being measured and what is the intake temperature? (Have I asked the correct questions?) The way I see it, HP, torque, pressure, and intake temperature are all inherently linked.

BTW: I have not seen an answer to the OP's question posted.

 

DOHC has half the posts of this thread and the least amount contributing. /Ban

 

ban? why? what did you contribute, man im sick of haters on this site, the reason why i said psi matters cuz once i accidently over boosted to 15 psi on stock motor and i bent a rod, but ya i no turbo size and hp play a part in this but thats if you have a small turbo if you have a bigger turbo and boost too much, you cant expect for it to last you right?but yes you can make lots of hp if you go with bigger turbo and boost safely, isnt reliabilty what we want here,not to blow his motor up?ive seen 300hp plus on stock blocks but didnt last long thats why i said to boost safely cuz im sure he wants his motor to last him right?

 

PSI is irrelevant, HP matters.

 

I dont see why you guys are hating on DOHC all hes trying to do is help, i say you just lock this topic now.

Truth

 

man you guys arent getting the point i no what you are saying is correct but you need to boost safely according to the hp and turbo you have, you cant go boosting 30psi and expect ur motor to last forever

 

I'm currently seeking a mechanical engineering degree, however i havent installed a turbo on a car, but it makes most sense to measure pressure at the intake manifold, this way you get the general flowrate after circulating all four cylinders, yeilding most accurate results.

Fixed

 

Just to let yall know i am planning on puttin a t3/t4 tdo5 turbo with ram horn manifold would this be good on my motor
and yall dont be ******* arguing i am just asking for help not to start fights

0psi. That's the truth.

I've discussed this a lot before. Turbo setups are seldom (closer to NEVER) reliable unless you spend a **** load of money on them. But I guess that depends on your definition of "reliable".

Hint: Honda offers factory warranties ranging from 30k - 100k. No peiced together or built setup offers that.

Why do u say 0psi of boost what makes my motor unable to boost

 

i'd say 8psi would be perfect =D
