After long consideration I have decided to upgrade the hpfp and get a custom tune. I'm going for the Full E85 by Cary Jordan and they said I should be looking around 500whp-540whp. Any tips on running this much power on N55?

let me know how that goes. they have had nothing but trouble trying to get my car to run on full e85

I'm not familiar with the Vargas, but 500-540whp seems high for a stage 1 turbo. Assuming the turbo is good for that power goal at full E85, keep in mind that you might encounter LPFP issues at 500+ whp if you're still on the stock LPFP depending on the tuning strategy.

I'm doing about 600-620whp on full E85 on a Walbro 525 lpfp and it's about at the limit.

Good luck with that. Vargas write 45-70whp over stock on their own website. Cary is quite the sales man

Won't happen on a stage 1 turbo, you'll need a bigger turbine, I believe the VTT stage 1 is only slightly bigger compressor.

[Daleb]

You’ll need a stage 2 turbo to make that sort of numbers.

Peter at pure turbos eu makes 530-550whp with ps2, upgraded hpfp and a hcp map on most of the 35i engines they do. Solid recipe to make that kind of numbers.

must be using the same dyno as this guy

https://www.2addicts.com/forums/show....php?t=1859639

• Drive to your nearest e85 fueling station (with a low level of fuel in the vehicle - preferably almost empty)
• pump 2 gallons of e85
• pump 2 gallons of 93
• flash over to bm3 stage 2+ e30 map
• drive tamely ~5 miles
• the next 1-2 miles get a little aggressive so that you are hitting some boost
• get ready to record a log
• go full throttle and record log
• come back and post the log

If the log comes back good and you aren't happy, go get your custom e85 tune from CJ for a little more oomph.

I'll just add +1 to basically everything above:

1. Reaching 500whp with stage 1 turbo will be very difficult/impossible

2. Full E85 will require LPFP upgrade, which potentially requires EKP upgrade as well. Stock LPFP runs out of steam around E70 on stock turbo, maybe a little earlier for you. Plus, lots of diminishing returns after about E50-60.

3. Try the BM3 stage 2+ OTS map before you spend money on a custom tune. (With HPFP and around E50)

this is all accurate and I've verified this personally

[ZM2]

And it’ll only get you 440-450whp. What’s another 100?

I concur. DO NOT waste your money on a custom tune for N55 (especially on stock or stage 1 turbo) ... run stage 2+ E30 octane tune with E50 fuel. I will summarize my experience...

Paul Johnson E50 Custom tune (stock turbo) --- 408 whp
PTF Stage 2+ E30 tune (with E50 fuel) --- 415 whp

I also wouldn't trust any tuner that tells you they can make 500whp on stage 1 or stock turbo, even with fuel e85. Max HP on stock or stage 1 turbo is probably 430whp (stock turbo) and 460-475whp (vargas stage 1).

Yeap, unless you have PS2 or more (GTX800/1000, Speed tech kits, BigBoost kits, Pure800 when they release) custom tunes are fairly à waste of money, the OTS maps are built fairly good, and if it runs like crap with the correct supporting mods and fuel, send a ticket in and the PTF guys will revise the map for you for free.

+2 on EKP

.

The manifold itself will flow enough to reach those numbers, but I'm not sure the compressor and exhaust wheels on a S1 will flow that much.

Probably hit reversion (exhaust gas backed up into the cyclinders) and sky-high exhaust gas temps before you get that much airflow through an S1.

Im on PS2 LPFP HPFP + Meth, 93 made 500 flat on my dyno, I think the stage 1 turbo will blow if you tryn to run it past 450WHP,

If my tuner suggested me to run something like that knowingly it wouldn't/Not meet my goals and have me pay, I'd have major trust issues.

Send Cary your mod list and he'll let you know how much power his map can safely make

He already did and was quoted some inflated numbers.

Ah, I did not realize, "they" referred to Cary. My bad

I have a similar setup but w PS2. See below. Question is do you guys think I need the turbosmart diverter instead of the BMS bov adapter and is the ekp needed with my fp upgrades? Also should I run eXX mix or 110oct for Dyno max pulls?

Dyno on 12/3/21.

Race gas will work fine for dyno pulls but E85 mix is more sustainable long term.

You need to check with Walbro on the demands of that LPFP to see if it requires a EKP or not.

I'm not clear on when an aftermarket EKP would actually be needed. My Precision Raceworks Stage 2.5 v2 LPFP uses a Walbro 535. Precision Raceworks specifically says that no aftermarket EKP is required.

when you run a fuel-it setup it's 100% needed. nobody is sure when it's needed with other setups because everyone else seems to do it correctly.
