I’m posting this in the Alt Fuel forum, as I’m especially looking for input from active E85 users and tuners. My current mods are:
BR cone filter
BR SS MAF pipe
Hallman MBC
APS dual vent BOV/DV
Helix down pipe
Helix test pipe
Greddy EVO2 cat-back (modified to full 3”)
HKS 264/264 cams
Nisei LICP
Walbro 255Lph fuel pump
IX turbo
PPI ported exhaust manifold
SS ‘eBay’ O2 housing
ETS 3” FMIC
1,000cc RC injectors
E85 tune by Scot Gray
394whp/418trq at 28psi on RRE Dyno Pack ???
My primary objective is torque. As you can see on the dyno graph, by about 3,600 rpms I’m already hitting 400 ft lbs. Engine is very responsive. Runs great; no issues. Car is street only. Daily driver. Always puts a smile on my face.
My questions: Are there any current mods that could better serve by being replaced? Are there any mods I’m missing?
What I’m considering:
1. Upgraded wastegate can. Either Forge or FP. I’m leaning toward the
FP WGA. Questions: Will an 18 lb can increase torque, or mostly HP? Will spool-up be improved at all?
2. Coil on plug–COP. I’m liking the low-tech Spark Tech setup.
COP w/o CDI. Right now my plugs are gapped at 0.018”. I assume with the COP I could run a wider gap. Would that add any measurable torque? I’m guessing, “No”.
3. I’m frustrated with my DV/BOV situation. I have a collection of these. I thought the very expensive APS was the be all end all. Meh!!! I’m considering the also very expensive
Works-improved OEM DV, especially since it is on "sale". Appreciate any input.
4. Thinking about converting to ECU boost control. This might broaden the torque plateau, especially considering what Tephra has planned for
Ver 6. What do you’ll think?
What I’m not considering:
1. Cams. Yes, I know bigger cams would give me more HP. However, I doubt that another cam can give me substantially more torque. But I’m open to input on this one.
2. Turbo. Pretty much the same comments as cams. Turbos are even more
expensive, and I’m not sure I would get any substantial torque bump. But I’m open…
3. Long-tube header. High rpm HP only, me thinks. Although, I’m watching the development of the short-tube header market. <yawn>
The Nasty Habanero.
Thanks in advance for your feedback.
