This graph is of a 84x87.2 B series, B16 ported head, AEBS IM, 12.5 CR, 70mm TB, JDM header and 2.25 exhaust.



Now with B19 1 piece coated header, 2-1/2" exhaust and Prototype Racing velocity stack.

 

Wow, that is a impressive gain.

 

wow... very nice gains.

 

Jeez, another great header from SMSP. I hope mine will be something close to this great work!

 

Dang....thats hella good.

 

Almost unbelievable. I cant wait till i get done w/ college and get a real job so i can afford to actually build my motor. Having no money sucks.

 

what cam was used in this motor?

 

Was the motor refreshed or just bolt ons changed? Impressive gains.

 

Hell yeah.

I see its a dynapack for both sheets but was it the same dyno?

 

nice numbers but doesn't church's read 10% higher than other dyno's..

 

Damn Dave thats awesome!

Yes it does BUT when you are showing gains from one setup to the next and it was done on the same dyno, you are looking at the gains , not the overall #'s
Look how much the header and intake picked up..thats insane..(but i knew about the smsp secret for years now, I run one )

 

nice

 

agreed, the gains are massive, nice one dave

 

so first that 1.9L engine was sucking air through a filter, and trying to exit exhaust through a jdm itr header and 2.25 exhaust..

now you took off the filter, put on the prototype velocity stack with no filter, and put on your header with a 2.5 exhaust..

with tuning, gains seem about right.

 

so these two runs were done a year apart? (judging by date on dyno sheets)

impressive ****!

S2S2 cams

They were a year apart but both done at Church's so I assume it's the same dynapack just at different locations.

Same engine, no refreshing that I know of.

I assume there was a filter on the PR velocity stack, but I'll check and get back to ya.

 

why cant we ever get dyno numbers on a stock motor compared to stock with aftermarket header.

because alot of people don't wanna waste money dynoing when all they have is an aftermarket header on a stock motor LOL

but..there probably has been a couple..just gotta search..or maybe start your own thread asking for it.

 

Nice numbers... The numbers are pretty close to what I made...

What is the CR?

OK, just got word back from my customer.

So adding the B19 header and 2-1/2" exhaust to the engine that was already running the ITR snorkle jumped the numbers from 208 whp to 233 whp. The unfiltered prototype racing velocity stack netted an additional 6 whp to 239 whp as shown in the above graph.

So the B19 header and 2-1/2" exhaust only increased power by 25 whp and not the 31 whp as shown in the graph.

25 whp is a very impressive gain

 

looks good dave
