Any Trickflow track performance examples available?

[Brewzer67]

Now that the Trickflow's have been out there for a while, does anyone have any track times to share? Since we don't race dynos I am curious what kind of track numbers they are producing and the combos that are running them. It would be interesting to see if a 600hp Trickflow engine produces 600hp times. I'd also be curious how they compare to similar Indy and Edelbrock builds. I once had a set of Stage 6's that way outperformed their specs. They were standard port versions that flowed [email protected] but propelled a 4600 lb. Cordoba to 10.40's.

Does anyone have any examples to share?

I would think racing dynos would be a more accurate comparison, lol. Car weight, converters, gear ratio, tires, tuning variables like elevation, DA, water grains all make track comparisons sketchy at best.

 

[Brewzer67]

Agreed to an extent. The piece that I like to see from track numbers is how tolerant an engine is when the total combination is off the mark. To show an example, I know a number guys in my area that over the years ran Chevy 383's that made great numbers on the dyno but just struggled at the track until the had their combo nearly ideal. Then there were the guys I knew running Mopar 383's making similar hp numbers that were way more tolerant of the wrong converter or gearing. I know that for the most point it boils down to area under the curve and that is what I feel you can see easier in real life application rather than trying to compare dyno points across that many different builds. It's a lot like when the O-ring failed on the space shuttle many years back. When you just looked at the actual data the failure rate was insignificant. When you looked at real world performance it was blatantly obvious that it was doomed to fail that day. Visually plotting the data showed that at those temperatures the failure was almost guaranteed. Unfortunately no one ever did that.
I was also part of some development testing years ago on skateboard trucks made of some high tech aerospace materials. Lab measurements showed successful stress tests exceeding 180,000 psi that when subjected to a 110 pound 12 year old using them failed well over 50% of the time. Sometimes data on a sheet is better looked at in real world use.

The TF240 headed, hydraulic roller, pump gas 537 I did has gone 9.97 in an A-body. I don’t know what it weighs.

Thanks Hemirunner. Any info on the build? OOTB heads or any additional work? Cam, etc. Just trying to get a feel for build to ET.

Thanks Hemirunner, good info. Anyone else with any examples to share?

Not a TF240 build but 1 with MCH ported Eddy's that flowed a similar [email protected]>
My mates 3150lbs 440ci Dart, 12.5:1, DC.590"[email protected] sft, Victor intake+adapter for 1050 Dom, SS springs, good dble adj shocks, 4.56/13x31's, 5000 stall ran a best of 10.14@132 = 597fwhp.

I have read so many posts, articles, and reviews about TrickFlow 240s and 270s that I can almost quote them.
I can't remember one, not one negative review, and most of the reviews about the heads are outstanding, and a lot of people also speak highly of the TrickFlow product and company in general. I know that's the heads I'm going to use.

 

[440rb]

Agreed, shame the guys over here haven't woken up to them yet, and I've done plenty of posting on my f-book page about the merits of 'em, they are better ootb than std. 440-1's.

Your right ,I'm not saying that they are the "Be all ,end all" heads but
Iv'e never heard anything negative about them. Going with the 270's myself. I was a little worried about my intake choices concerning m.w., and limited hood clearance. Went with an Indy dual plane ,deep port matched ,m.w.intake from Hugh's. Hugh's states that intake in standard port version flowed about 359 ,the max wedge numbers ( he couldn't find at that moment ) should flow more. The 270's flow around 343@ .600 (my cam's lift) .So this intake should be 10 percent or more than the heads at .600 if Hugh's numbers are close. I'm thinking more 270's will find their way onto street motors.

Speaking of...
It may take a while, but I have decided to go with a Bill Mitchell aluminum block, and I've been advised to do a 4.25 stroke, and I'm selecting the 4.5 bore, so at 541 cu in, I'm going to use the TF 270s. One parameter that I insist on is a 3x2 induction for my V-code Roadrunner, so the 270s and a Indy ModMan intake seem to be my best choice of only a few.
I want to keep and use my N96 hood and Air Grabber, so taller 3x2 options are off the table.

Why not 4.500 stroke and 572 cubes?

So far, AndyF is the only one I asked.
Also, more street than strip action, and I already have the potential to make more power than I could ever use or handle.
I'm open to advice.
Ultimately I will consult with my builder.
This will probably take longer than I'd like it to, but I've weighed the options, and an aftermarket block is the way to go for me, so I don't have the worry of block breakage or a 600-700HP ceiling on how much power I can generate, and walking that line be constantly worried about block failure. Aluminum is not that much more that cast iron, given the overall cost of the build, so that's a pretty easy decision.

I only asked because I prefer the longer stroke in the street engines as the added torque at lower rpm is so much fun, however, you’re at a disadvantage with the fact that you try to race that thing with a street clutch. The added torque is just going to make your challenge that much greater. This is really where I see you coming to a fork in the road....

Only if it's a clutch fork..
Actually I already bought a Hydramax hydraulic throwout bearing, and I am going to get the HitMaster hydraulic launch control system as soon as I can, and ask McLeod if they think it's worth trying my current street/strip single disc and 2,900# diaphragm style pressure plate combo with it, IOW is it going to handle my CURRENT motor and a little off the line higher RPM slippage.
I am sure that when the stroker goes in I'll probably get (or maybe have to have for track rules) a scatter shield bellhousing, and I'm guessing some kind of dual disc clutch.

With that kind of power, you’ll need a soft lock clutch. They can be used on the street but the maintenance (and expense) won’t be fun which is why I think you’re at a fork in the road. I’ve watched the progression of this many times before. After the same experience as most running a 4speed and a street twin, I skipped the lesson and the expense and went straight to a 727. I should’ve just gone TH400.

Thanks Hemirunner, but having a 3 pedal car is a MUST! No auto trans allowed by my own will! Infinitely adjustable stall speed...
I am going to put the 700 continuous Ft Lbs torque rating of my a855 Passon 5 speed to the test!

I admire your dedication to it!! I’ll be watching the results!

I would agree. I really like mine but don't have any results to share yet so I was hoping some others would. There are lots of folks that have shared some great Indy headed examples of builds and what kind of times they run but I haven't seen to much that way from guys running the Trickflows. That's what I was hoping this thread would wind up like. I'm looking for a kind of a "Post your 10 second combos with TrickFlows" or "Post your 9 second combos with TrickFlows" thread. I have founds lots for Indy and for Edelbrocks, but not much from Trickflow users.
