With only 7 lbs of boost available, wouldn't 56lb injectors work just fine? It's not like you're going to be making a ton of power.

 

[Heaten m90]

Shit man I don't know, I just figured 80's would work.. I was looking at one of my logs and I went 0-60mph in 3.6 seconds wonder what it'll be if able find this missing power

 

[deebo05]

that thing needs timing its only at 19* on c16.

 

[Speedboosted]

It only made 6lbs of boost with 19* of timing through an M90 and you're wondering why it made low power? Bruh, that seems about right. Especially if it was a dynodynamics or mustang dyno.

 

[Heaten m90]

I've read of numerous people making over 400RWHP on a mustang dynos with similar setups.

I looked at your 1st to 5th log and saw 21 degrees at 5k rpm and it dipped to 20.25 by the time you let out (also 167mph top speed is impressive with just 366whp). And 12.6 AFR is lean so maybe it just needs more fuel.

I would look at weak links in the mechanical areas. What is the vacuum gauge reading at idle and does it behave like it's supposed to when you rev the engine?

Also make sure 0 degree plugs are installed with the correct gap (.030 - .032 is a good starting point) and do a compression test.

If all of this checks out, make some passes at the 1/4 mile track and see what trap speeds you're getting. Trap is a better indicator of power/weight than a dyno number.

Me and lito are almost done with the 93 tune and the car is an absolute fucking animal. In second the car breaks loose and I'm on slicks. I broke 180MPH and had more in it but I didn't want to take it over 7K RPM. It seriously feels like a 10 second car. I'll do a compression test tomorrow just to make sure. Can't wait to see what E85 does!!! Thank you Lito!!!!!!!!!!

How tf do you go 180 MPH, not that it's not a beast I'm sure, but 180 MPH just seems insane, lol.

 

[Heaten m90]

Well max speed of a 3650 is 202 MPH at 6K RPMS (i think) and I was at 6.5 K with 4.10s on A7's. Fuck'n warp speed man!!

 

[RocketcarX]

What size back tire are you running?

 

[RocketcarX]

6500rpm with 4.10s on a 27 inch tall tire is right at 190, so you were def some where around 180, man. Good night thats fucking fast!

 

[46addict]

Wow is anything done to it aero wise? How does it stay on the ground? lol

 

[Heaten m90]

The A7s have a very low profile, the front bumper is only about 2 inches from the ground. But it just has the 427R body kit, no hood right now. My VIS carbon fiber Super snake hood has been on order for 2 months now, should be getting it within the next week or so... I still need to install the tubular kmember and front and rear bumper deletes to be at max weight reduction.

 

[redfirepearlgt]

So to ask a stupid question....how much weight does the "bumper delete" remove and does it keep the air bags still active? I know the K-member is worth about 47 lb as I recall. Thanks.

 

[Heaten m90]

About 35LBS, air bags would be fine

 

[46addict]

35lbs from each end?

 

[Heaten m90]

35lbs total loss

 

[Heaten m90]

The weight off the front end helps a lot though

 

[Heaten m90]

The E85 is out of this world Lito really knows his shit!!! I think I have the fastest 3v M90 car in the world.... dyno next week then the track I'll post my results. Getting 26 degrees of timing now
