my dyno today(base for e85 tune)

UPDATED 6/9

The temp was 95*, car has a little over 5k miles, the only mod are exhaust and long tube with no cats, and the newest trifecta tune. The dyno was a dynojet 248x inertia 2000hp chassis dyno located in beltsville md@SRT home of the fastest lexus is300.

I do not have a baseline for my car, but others on the same dyno produced around 232rwhp stock in 90+ heat, and around 240rwhp in a cooler 50's.

I dynoed 264rwhp and 240rwtq.

The reason for today's dyno was to get a baseline established for trifecta's e85 tune I am currently testing. So far so good! With the proper timing, AFR, and control of valve timing VVT, we can manipulate the effective compression to take advantage of e85's 105 octane and its cooling nature to pump out more power than what a usual N/A car can do.

Those numbers do seem a little low for your mods...That means you've only gained about 12-15 HP.

Did you do a stock dyno? If not, there is no way to know how well your mods have performed.

Lets just hope that vince can tweak our fuel to pump out sufficient e85. I cant wait either

Anyone with more dyno experience want to chime in? the owner of my dyno shop said that his dynojet is a bigger model that reads lower than the usual dynojet. whats your thought?

Oh.. and forgot to mention. today at 4pm when I got my car dynoed was 90 degrees on my radio before I went in. very very hot day.

you know what, after doing some searching/researchin on this forum it look like most peoples with manual are putting down 260-270hp with added intake headers, exhaust, tune. Remember, I have no intake yet, I am still waiting for vararam.

Stock is usually seeing 245-250 manual. so if I did 270hp with stock intake than I actually think thats a ok number. Plus the owner told me that their dynojet is a bigger model and it read lower than the usual dynojet. So if thats true than that mean even my 270hp number is really conservative right?
and I think if I would of kept pulling I could of even got higher number. The dyno run went from 265-268-270, so I think I could of got higher figure because the power was just getting bigger with each pull.

Also, vince just got back to me and said this:

Vince Geglia (Trifecta Perf.) to me

show details 7:34 PM (2 minutes ago)

Those numbers are very good, I certainlywouldn’t be unhappy with them. Most guys were getting less than 260WHP withyour level of mods on the old tune.



- Vince Geglia
TrifectaPerformance, Inc.

Thats very interesting.

Well at least I have a base figure for e85 tune. Thats all it matter no more need for guessing.

My shop that I go to says the same thing, lower reading dynojet. But probably more realistic instead of pumped up numbers.

The H.P. seems right on with others that have LT's and exhaust with no intake.Doesnt seem bad at all.

I actually think the numbers are good. Considering a stock v6 usually dyno 240-250hp the highest on a dynojet than that mean I could of gained anywhere from 20-30hp. The only thing that I could of got the extra power is from the long tube with no cats and the new tune. So if I look at it that way than I think 270hp on a 90 degree weather is actually good still with factory intake.

At this point the number really dont mean crap since I dont have my car's stock dyno to compare with. What matters now is that I can now almost correctly see the gain with e85 tune when I go backassuming that the e85 tune will work on our car.

I was almost with you until I realized what stock v6's dyno on other similar dynojet. I think its more 20-30hp I gained considering stock see 240-250whp.
but again, I cant really take the numbers from today too seriously without having base numbers to compare to.

My best was 270hp with all my mods, minus the nitrous. So you are good.

That's with ss wheels as well, which effect the readings with heavier wheels.

If it's at all possible, best scenario would be to run a baseline dyno when your low fuel light comes on, then run to the gas station and fill up e85, and run it again. Not sure if that's possible.

Definitely DO NOT be unhappy with those numbers. Heck man, first off your right in there (pretty close) to what other guys with your mods are running (minus the fact that most of those guys are driving automatics), but you gotta keep in mind on top of that your dyno guy said that dyno typically reads a bit lower than other dynojets, AND it was hot as heck! So you factor all that in, and your doing well.

If your car was an auto, you would have probably dyno'd 10 HP less than that. Be proud, that your driving a V6 putting around 340HP/300TQ out at the crank (well maybe not that much on a HOT day lol)....maybe even a tad more.

If I was you I'd go back on a cool day or this fall when its about 50 degrees out and give it another go...of course if your E85 tune works, you'll be makin even more power.

But would the E85 tune need some drive time as well to achieve best results?? Iono

Good question. I was with him on this for TRUE contrast results, but does the computer need time to adjust? One for Vince.

Well, Vince has said it does need time for his normal tune.

kmprenger you are right. For some reason I thought that our stock v6 dyno around 260hp. I dont know where I got that from. It must of been the heat boiling my thought process.
I didnt realize that my dyno numbers are actually really good until I started seeing past posts of other peoples stock and similar modded dynos.
Im not too worried about todays number anyway. After all todays dyno was just to setup a base number in prep for e85 tune. Im happy with my performance so far regardless of the number.

poorman, I have to empty out the 93 gas as much as I can and after that I have to at least go through a tank or two of e85 to effectively be converted.
I am just hoping the tune can compensate for the extra 30-40% e85 to give the same gasoline effect. Vince seem optimistic about it.

If this work than I am almost sure we can see 300whp - or + without going FI. I am just lucky to have plenty of e85 in my area.

Also, I have to take into consideration that the e85 will have to be tweaked out with datalogging in between unless vince is just that good and can get it on one shot.

Don't worry so much about what the actual number is. Your right in the range you should expect and the dyno is just a tool. Your looks to see how this new mod (E85 tune) will improve over what you have now. The true test will come at the track.

With the stock intake you could have been pulling timing as the sensor really heats up.

Im not too worried gretchen. My main goal for this dyno was to get a base number for e85. Even if I was to take yesterdays dyno number seriously I think I could have seen up to 280whp and maybe even more if the weather was cooler and if infact what my dyno guy said was true that his dyno read lower(2000hp 248x)but what surprise me the most is that these numbers are with my factory intake.

After everything is setup and completed I will hit the track and get some numbers.

its always a possibility but I am def not getting the full effect of my header due to my restricted factory intake. Theres def more power to be had. 300whp does not look too far away

Silly me...I assumed you had a CAI to match the flow on the bottom end...
