Has anyone flow tested the trickflow 190 heads yet to see if they stand up to the numbers trickflow posted?
 
Imm engines has,the results are on his facebook page,you might check with Mike at b3 racing engines as well,I am sure there are others.
 
I saw where IMM posted on his Facebook page about 1 intake port and 1 exhaust port but had not done the whole test yet. I didn’t see anything else on them.
 
Tested on a bench from a reputable shop, under the same conditions that they tested them with ....... how far off could the advertised numbers from TF really be?

Enough to where you wouldn’t buy them?

I’ve tested a number of the TF BB heads, all were very close to the advertised numbers.
I’d be very surprised if the SB heads didn’t follow that same trend.
 
Dwayne is a little more diplomatic then I will be---What does it matter? Who trusts who's bench? So I post my results of TF's heads and they aren't anywhere close--What now? J.Rob

You have a stingy bench ? lol Do you have the TF 190 #'s from your stingy bench ?

Would be nice to have some sort of comparison, then make a judgement call from there.

Yeah, it's not like tons of people have asked what others are getting for flow numbers on other heads and have been met with such assholeishness. This beats anything I've ever seen.
 
Well I’ll say it: the trick flow 190s are barely any better than the Procomp /Speedmaster 190 CNC heads. Kim

Before you answer, just know that I've flow tested both heads, and built engines with both heads, and dyno tested both heads on engines in our shop....

Actually RRR there are TON'S of threads where people are asking/providing/disputing flow numbers from cylinder heads. I'm also fine with being called an asshole, I've been called much worse by people I've actually met and care about.

Here's what normally happens with a cylinder head thread---
Dude 1 asks what a certain cylinder head flows
Dude 2 answer with that head flows X
Dude 3 says that's B.S. 'cuz on my buddies bench it was way lower/higher
Dude 4 says Yeah but they do/don't make any power on the dyno
Dude 5 says I don't care about the dyno, only the ET
Dude 6 says but what about this other cylinder head
And back to Dude 1

Yeah, Brian but you and I both know the real cool cats don't dyno their stuff. J.Rob
 
You wanna hear something? I've flow tested many cylinder heads on my bench which is about 40 feet from my dyno cell. I've tested many engines with the very heads that have been tested on aforementioned bench. I've seen dyno results that lead me to believe the cylinder heads were underperformers in relation to the observed flow numbers/curve (oops theres a hint) . I've seen dyno results that far exceeded what the flow numbers would indicate. I've also seen many dyno results that I thought were bang on. Now I am getting a pretty good handle on all of this but until I can establish a trend the flow numbers of a head don't really tell much at all other than maybe potential, maybe. J.Rob
 
Not sure who or why someone suggested a 2.02 valve in the TrickFlow heads but that would be the first upgrade I would do. It’s not the 1970’s anymore.
 
Dude 5 says I don't care about the dyno, only the ET

One of my personal favorites.

Cuz everyone’s car is 100% sorted out, along with track and weather conditions not having any impact on the cars performance.

Put your 750hp 540 that makes peak tq at 5200, peak hp at 7000 in a 4000lb 71 fury with a 12” converter, 2.76’s, and open rear end....... compared to an 1800 dragster with the correct converter and gearing, and I’m sure the numbers would show the motor is making the same power in both combos.:realcrazy:
Uuhh...... ain’t gonna work out that way.
The better car makes the numbers look better.

My point with the flow numbers was.......when you look at flow data from different benches, the only thing you’re really comparing is, especially when it comes to CNC ported heads offered by a manufacturer, the flow benches themselves.

If you brought one head to 10 different head shops, I’m pretty sure you would end up with a pretty noticeable spread from the highest to lowest.

Unless you have a database from a bench that you’ve used before to be able to compare the results with....... it’s just numbers.

When the TF 240 heads came out there were a bunch of results posted.
I saw one shop that had the numbers noticeably higher than what others had posted, and they were also higher than the advertised numbers.
At that time I had already tested 4 heads...... and all were within a couple cfm.
These other numbers were about 20cfm higher.
There is NO WAY the head flowed 20cfm more than the 4 heads I tested.
In other words, tested back to back, on the same bench, both heads would have been within a couple of cfm.

So, the 20cfm higher numbers might make you feel better....... but the head itself isn’t really any better.

If you get enough test results from various testing services...... and you need to see a certain number to make you feel good about hitting the “add to cart” button....... eventually you’ll get the answer/number you’re looking for.

If I had tested some, I’d post the results.
But IMO, that data would only be directly comparable to other test results from my bench.

I had a customer of mine from out of state get a couple of heads flowed at a shop near him.
Two different heads that I’m very familiar with.
The numbers are waaaaay off. Not way high......way low....... like 40-50cfm low.
There is no way they flow that little........ either the bench is way off, or the testing procedeure is wrong...... or both.
The numbers are useless for trying to gauge how they stack up compared to most of the rest of the world.
They are only useful if you did before and after testing to gauge your progress.

If 3 people responded to this thread...... with the results being 320, 305, 292........ would that really be of any help in deciding to buy them or not?
