Eric has a solid ford rear which should net him some mid to low 1.4 60' times.
I ran 10.70's with 440rwhp. (weighing 2800lbs) A low 10 surely isn't out of the question.

 

your a exception to the rule

maybe its cause FD's have a better chassis
but forcefed's street TII with 560 HP ran 10.7@131
tearbo2 with 540 HP= 10.6

my tuners FD 2900Ilbs with driver..... 570-580 HP = low low 10's to 9.98

with the solid axle he can drop the hammer
thats true

 

I am not hating here, but the numbers are not adding up. Either your are running a high base pressure or there is an error in what INJectors your are running, the duty cycle, or the RWHP (or Max Cooper's fuel calculations estimates.)

You would need to run a base fuel pressure of 53psi with 950s+1300s, to get to near 533RWHP? And let's not forget AFR and how it plays into the equation. This is assuming the setting of .60 HP*lb/hr for super turbo rotary.

Love to learn from your situation and see the dyno sheet.

 

My number was after the correction. Not bad though, I started out at 370 whp and ended at 533whp

 

21 degrees @10psi,
16 degrees @ 16psi
15 degrees @ on up.


12 degrees neg split.

 

Yes, we're planning on getting Steve back to St.Louis before years end. I'll have a better boost controller and bigger wastegate spring when he comes.

 

MBC, it's the ball and spring type. I'll probably just change the spring.

I only have a 10psi spring in my 60mm wastegate so I def need a bigger one.

I'm going to try and hit the track not this tuesday but next.

I'll post the dyno sheet when I can get ahold of a scanner. My computer at home is down so it might take a few days.

 

48-50 psi base

AFR's were in the 11.7 range.

 

Car weighs around 2630 with me in it. My fat *** needs to go on a diet.

 

Yes, I posted that earlier. When dynoing, steve thought something was wrong because my car was making more power that it should. He then took a look at my fuel pressure and base was right around 50psi.

Inj duty was at 80%
Injectors are 1300's and 950's.

AFR's were right around 11.7

Fuel pump, Aeromotive A1000

 

Tear 'em up! Nice! Thanks for the info.

Was Steve happy with the 11.7's? I take it this is a bridgeported engine?

And the ambient air was 100f? Tell me you have water injection.

 

You mean IGT was IGL-12, not IGT was -12, right?!

 

IGL/IGT split was 12

I suck at the typing

 

Steve was happy with 11.7 since he tuned it to that Motor has a large street port, I used a ITO port template.

The temperature of inside the building was 96 degrees. I forgot what temp my engine ait temps were. My water temp wouldn't go above 68!!! We had to unplug the fans.

My water or meth injection....

I also was using ngk advance auto cheap #10 plugs.

 

damn!!!! thats got to be one hell of a ride. wheres murphysboro??

 

Is your 60mm gate the one where you can tighten the screw down and thus create a larger spring boost pressure?

Guys you have to remember, he is on VP C16 race fuel, which has a greater specific gravity than regular pump fuel, thus he is able to run lower duty% and still achieve the same safe air fuel ratios.

Good work Gotham / Lupe

What altitude? The correction factor to SAE during my runs was 1.01, basicly nothing for a 91* day. 360 to 414 would be a 13% correction, that is a huge number, can you explain? Not bashing, just trying to learn about the different dynos. I guess with the Dynapack(I know you were on a different type), and similar dynos, there is alot of info to configure, If you get a chance, a dynojet # would be neat, so we can compare results to other cars. What clutch are you using? I just tried a Spec Stage III, with a 6 puck, and it is not even close to holding full power. Anyway, I love your car, show and go, excellent. If you ever want to compare notes, my number is 707-696-2705. Best regards, Carl

 

The DD reads about 15% lower than a dyno jet.

 

Before all you guys go nuts please get the info from the guy that tuned the car. Namely Steve Kan. I talked to him at the airport on the way back today and he would have all the details.

Those were great numbers and u did not blow it up.

Ken

 

whats the most that he said you could boost? Nice numbers. BTW what clutch & flywheel are you using, and the fuelpump?

 

Just got back from the trip. What a weekend. I guess I need to straigthen out some of the questions people have here.

frist. the dyno we were putting out extremely low #'s. According to the owner of the dyno, he said that he has the tech came to his shop to figure out why it was doing it. Basically, the tech couldn't figure it out but they estimated that the % is around 5% lower than their other dynos. when compared to dynojet #'s, you're looking at 20% lower #'s.

Lupe's car was the first on the dyno. The most we managed was 445rwhp@23psi. with the 20% estimate, it made 533rwhp when compared to the dynojet. The car was running 950cc/1300cc injectors with 50psi base fuel pressure, C16 fuel and 80% duty cycle. a/f ratio was around 11.5-11.6

The very next car was a street ported engine with stock turbos. We made 252rwhp@13psi. with the 20% estimate, it made 302rwhp. That sounds about right with the mods he has and the map I was using as a base line. a/f was around 10.9-11.0

next was another stock turbo with stock ports. It made 230rwhp@13psi which translate to 275rwhp. (sounds about right since he has a high flow cat). a/f was around 10.9-11.0

next was a car with the GT35R turbo and a ported engine. The car made 322rwhp@15psi. with the 20% estimate, it made 386rwhp. I think this is the car that I feel has a restrictive exhaust system. (can't remember). a/f was around 10.9-11.0

next was a TII with Davichi turbo and haltech. The car made 355rwhp@15psi. This translate to around 426rwhp on dynojet. The duty cycle was around 82% with the base pressure of 45psi running 550cc/1600cc. a/f was around 10.6-10.9 (i tuned it richer since I thought it was making a little too much hp).

Those were the cars that was tuned on the dyno. I did the rest on the street since the dyno place was closed on sunday.

Now, its hard to say if the 20% estimate is accurate or not but based on the other three cars in the middle, it seems about right. The only way to verify it is to goto a dynojet or run some 1/4 to back up the hp claims.

Only time will tell.

 

Actually I live right outside St.Louis. Belleville IL. I haven't taken it out yet, I'm kinda sceeared

 

I think all I need to do is move my boost controller line to the upper wastegate port for higher boost.

No props to me, it would be a slow peice of turd if it weren't for Steve Kan.

 

"Now, its hard to say if the 20% estimate is accurate or not but based on the other three cars in the middle, it seems about right. The only way to verify it is to goto a dynojet or run some 1/4 to back up the hp claims. " Yup...

what does the dyno manufacturer have to say about the numbers, any explanation? What values does the software ask for when you set-up a car?




Lupe, do you plan to take your car to the track anytime soon? For the 1/4 mile gurus, what would 530hp/2700lbs equate to in trap speed? Sounds like the owners are happy, that's always the big one. See y'all at SS8 Maybe we can get a mobile dyno, or incorporate a dyno day????

 

Altitude is around 415.

This dyno is like no other. Like Steve Kan said, 20% is the right number. You'll get a trap speed before another dyno number. The next closest dyno is an hour away.

I'm using a act 6 puck with a 9lb alum flywheel. Yeah, it's no show car. I just wanted it to look different
