**UPDATE: BROKE into the 5's on E85 on ETS intercoolers (May 20/15)
- 60-130: start 225.89m finish 225.12m =0% decline, 1/4 fuel like most my other runs, same road and around 14degrees


4th: 5.99


Not really a big change as with my stock coolers as I did multiple 6.03, but it was nice to see a 5.99 roll up!!


I am now going to email Todd my logs and see if we can now tune for the ETS coolers on both E85 and pump to see if we can squeeze out some more power. My only concern is running out of injectors on E85 with any more power, but I will leave that to Todd.


Really hoping to pick up some power on pump as there was no change with just the swap of intercoolers in my 60-130 other then quicker boost recovering when going through the gears (60-130 only use 4th) and feels like the car pulls harder when I get into 5th from a 3-4-5th pull or even a 4th-5th pull, but I have no previous time comparisons from before past 130 or in 5th.


Hoping for 5.8-5.7 (If there is injector room) on E85 and 6.6-6.7 on pump after Todd tunes for the ETS coolers on my set up!!


We will see!

**UPDATE: BROKE into the 6's on stock intercoolers and pump
- 60-130 -0.5% Decline, 9 degrees, PUMP GAS!

4th : 6.90sec (-0.6% decline /0.59G)
4th. : 6.92sec (-0.5% decline/n/a G)
4th. : 6.96sec (-0.5% decline/0.64G)
3rd-4th: 6.97sec (0% decline/0.74G)
3rd-4th: 6.93sec (-2.1% decline "started late on this pull, hence the decline)/0.75G)


The reason I went out again before I do my intercoolers, is when I tested my 7.2's, this pull was in the same conditions as then. ie. It was 8-10 degrees out and I had a little over 1/4 tank of fuel. When I did my 7.0 flat's after Todd K's "more bottom end pump gas tune", it was 3/4 tank of fuel and 18.5 degrees out. I just wanted a fair back to back to compare the two tunes.


So I can say that I picked up 0.3sec from this latest revision tune as the conditions most match each other.


Now in 3rd -4th gear pulls, my car is consistently hitting 0.74-0.75G on pump verses 0.68-0.7's with the old tune.


Well hopefully I can get around to installing my 997.2 intercoolers SOON, and fingers cross for 6.7's on PUMP and 5.8's on E85!!

**UPDATE!! 60-130 -1.25% decline 18.5 degrees 94 PUMP GAS!!
3-4th: 7.02sec
4th :7.04


The only difference is Todd adjusted my bottom end tq by "moved clutch limit to match E85 file". Todd forwarded me a stock OEM tune (he just calibrate for my 80lb) 1.5 months back so we can try to diagnose a low boost issue I was having. When I got that file I was surprised that the OEM tune had so much bottom end tq / boost under 4000 rpm vs my Proto tune. I told him when I logged there was a big difference between the two under 4000 RPM'S. He then sent me this new file with everything the same as my current Proto pump gas tune, but "moved the clutch limit to match E85 file".


**that's a drop of .2 with just a revised bottom end tune**


I was hoping for a drop of .2-.4 in upgrading my stock intercoolers to run 7.0-6.8 on pump, but now I have hopes for 6.8-6.7 with upgraded intercoolers!! I should find out if my intercoolers theory is correct shortly, as I have acquired a set of 997.2!!!

After a year with out my car doing a body kit/paint (will do another thread with pics) and finding tuning gremlins....SHE IS ALIVE AGAIN!!!!


This is the thread of my progress from almost stock to MS 109 ON STOCK TURBOS:


https://www.6speedonline.com/forums/...ight-pipe.html





The only reason I purchased the VBOX when I had my 996 is to see real world performance increases and not just "the best down hill, bang my gear box out, stripped car for the run, wind behind me, vodo technics times..... but to see what if any a certain mods gave me power wise and or different shifting points in real world situations.


All my runs were down the same road, start around 38-40mph, start in 3rd gear, take 3rd to around 6300rpm, 4th to 7000/130mph, drive around a very big block to cool down and come around again and do it again. I took a three pull average and came out with the 60-130. I am looking for a repeatable consistent way to measure so I can see real time difference. I run Sunoco Ultra 94 with a bottle of NOS Racing Formula Octane booster per 40 litres of fuel (I put that in my fuel just to make sure that I always have at least 94points in the tank), full weight, no brake boosting.


For a reference this is my current power mods on my 997.1 manual:

PROTOMOTIVE 63.5
PROTOMOTIVE 94 octane tune & E85
PROTOMOTIVE 80lbs injectors with 5BAR FPR
do88 inlets
ERP TRIPLE clutch with LWFW
Speedtech X 3" catless race exhaust
GT3 Throttle Body
IPD Competition Intake Plenum 82mm
EVOMS under drive pulleys
BMC Air filter
**STOCK intercoolers**


Pump 94: 7.2 60-130. 3-4th gear


E85 : 6.0. 60-130. 4th gear (ran back to back 6.0, both runs almost flat /small up hill: 0.12 m & 3.7m)

6.1. 60-130 3-4th gear (as above on flat / small up hill)(these pulls in 3rd gear would just have ALOT of wheel spin/traction control killing power on my brand new sport cup tires!! I am 100% positive with warmer tires/day and no spinning/traction control 5.8-5.9 is there!!!)

3-4th gear was .83G's (least amount of wheel spin) & .75G's (with a lot of wheel spin!!)!!

I am very happy with the numbers as the car moves out solidly on pump and frankly the pulls on E85 took me by surprise as it pulled ALOT HARDER then I imagined and it was relentless.





5.8-5.9 is there for sure!




I would like to say thank you for TODD K for all his help, experience and helping me make a great street weapon!


STAY TUNED!!


Thanks

congrat buddy car must feel like a beast !look like a 5sec slip soon

Man I remember reading this back in 2012 when I had my Billet 16 996 and kept thinking when I ever get a 997, E85 is in my future...... yes that is when my addiction with E85 started!


This thing was pulling .83G on the 3-4gear 60-130 E85 pulls from my pump of .7G's!!

 

congrats on the numbers OP! enjoy her

 

I know! The first time I did a couple of pulls and felt the amount of pull all over, especially down low, I started of thinking about too much torque and rods!


Just be the seat of my pants pull, I called Todd the very next day and ask him to keep my HP up top the same, but pull out low end tq.


He assured me that this tune is fine for stock rods as it is below 1.6BAR and that is when he starts worrying about rods. He also told me that the tune is from a proven 911 member.


As per Todd:


"This was what Chris Tellekamp ran when they made like 675awhp out in NY and set some great records in his car with the similar config."


The way the car is feeling, I think I might still go dyno it when I upgrade my intercoolers, as I would really be worried then!


My goal with car was a street reliable car NOT tuned to the ragged edge and my only peace of mind is that one of the best / most experienced tuner (Todd K) has made the tune.

 

Congrats man! These cars take on a whole different persona as they drop into the low 6s, high 5s 60-130. Rockets for sure

 

7.2 and then 6.0 from simply switching to e85/tune is incredible.

Congratulations!

 

Thank you. I think I have watched everyone of your vids and your machine is truly a real street weapon!

The reason for the drop in time being so drastic is I am running the stock 997.1 intercoolers. On pump gas my VTG's are blowing so much hot air that my intercoolers can't cope and my IAT is what is holding it back. But on E85, the E85 is cooling the cylinders down that the IAT is not that much of on issue, but the 997.1 coolers are more of a flow restriction (cfm wise)for the E85.

When I upgrade my intercoolers I can see only a 0.2 reduction on E85, but I feel a 0.3-0.4 for pump gas as it lowers my much needed high IAT!!




Thanks

Love hearing about E85 success stories. Does everyone test their E ratings? Big change with its ethanol rating..

 

Being we don't have E85 at the pump, I order my E85 from VP RACING and it is called C85, for CONSISTENT 85.

 

Be very careful with C85 and proto injectors - especially the 1680cc/160lbs Todd sells. C85 has MBTE in it, which causes the seals in the injector to swell and a lose of 30% of flow.

I had this happen to me. Car went way lean and my AEM fail safe saved the engine.

Again - be careful.

 

what he said ...

also i would check your allignment and maybe look into upgrading suspension or finding a better road. my car has traction in all gears on 19" Super Sports.

 

congrats Bobby, that is a great result. Too bad the corn is so pricey up here.

 

Mark - can you give me some info on your alignment / suspension setup. Mine is rwd and gets pretty squirmy under power with the super sports. I think it's either my alignment or LSD is shot.
