I had 453bhp and 550flb back when the xdi35 was first realised

Thats good figures, a realistic 420/430bhp is all you would see without a hpfp upgrade.

Have you any 100-200 figures for that setup? would think it would be a low 8.

No bud. I have never owned a draggy or such. I have had many custom maps on the car and that felt the fastest on the standard turbo. It was quick

Can well imagine, are you on a larger turbo now?

Yes mate I running a tte550 now I have something different coming next month.

Obviously you’re going to blow this away with your TTE550.

But just to add another data point for everyone, I just drove my buddy’s M2 with stock turbo, XDI-35, and TTFS 93 octane tune, and my Stage 1 Dorch, Dinan turbo, half E85, and Halim’s new OTS Stg 2+ E30-40 was quite a bit quicker.

On a side note his suspension (M Perf) and exhaust (Akra) was much better than mine!

Sounds quick! Do we know if this new OTS will only be in e-mix form or will there be a racegas and 93 version too?

Also what sort of WHP delta are we looking at going from, FBO with stock map to FBO with stage 2+ e30/40 map?

Halim said a new race gas map is coming, but I’m not sure about 93.

I picked up 80whp on the same dyno/same day bn the stock map and FBO + Dinan turbo with half E85 in the tank, and the new Stg 2+ E30-40 with same hardware and fuel and just switching between maps.

It looked like the FBO hardware on the stock map + E85 in the tank was giving me 25whp vs everything stock/stock, so >100whp gain overall is not a bad showing!

I’m guessing the Dinan turbo only adds 5-10 peak whp vs the stock turbo with this tune, but gives a decent bit more power under the curve in the upper RPMs while keeping the spool instant. We’ll know soon once we get a stock turbo dyno on the new map.

The guys with bigger turbos are seeing much, much bigger gains.

Good to know, A stage 2+ Racegas map might be a bit easier for me. On the stage 2 racegas OTS map I just need to add a bottle of octane booster with pump fuel to run it safely.

A 80whp delta is great, I think these 2+ maps will be the sweet spot for me.

It would be cool to see some rolling dragy numbers on your car, from my experience a little more area under the curve even with similar peak figures can make a decent difference.

The oem turbo seems to hold 20psi to redline going off the virtual dyno logs posted by the other user testing the new OTS, pretty impressive.

I'll be getting my Dorch stage 2 HPFP, Fuel-It LPFP & Bluetooth flex fuel analyzer all installed next Tuesday I will also be hitting the dyno the week after next to get stock tune w/ FBO, e30 OTS map, and Halim's new e40 tune runs to see what kinds of gains can be made on stock turbo, FBO & upgraded fueling.

I'll be upgrading to Pure stage 2 when they get my turbo shipped in next 3-4 weeks and I'll do another couple of dyno pulls as well.

Looking forward to seeing your numbers, as this is the path I'm looking at as well. I put down just over 400HP on the OTS Stage 2 Racegas tune with FBO at a local dyno-day. If I can hit around 450 with the upgrades/tune you mentioned, I'd be super happy!

Are you also on the stock turbo still? I think I remember you saying you were on another thread (or maybe it was this one, I can't keep up lol)

Yeah, if I can reach 450whp on stock turbo, I'd be impressed. Though, I have a feeling that would really be stressing out this little turbo. Either way, I wouldn't try to run it at that power level...more like 425-430whp would be more feasible on stock turbo imho.

I just want to be at about 500-525whp & 550wtq. If I can get that on e40-e50 w/ Pure stage 2 and my other upgrades, I'll be completely satisfied...then I can finally be "done" modifying this car...maybe

Yup. Stock turbo. Plan on doing Pure Stage 2 at some point.

Glad to be the guinea pig for someone with similar mods I've definitely benefited greatly from watching others' builds, so if someone can learn from mine I'm glad to help

Go stick it on a Dynocom like some of these other “high horsepower” stock turbo cars and you’ll hit 450whp.

Dynojet is more like reality, and Mustang’s will just make you cry.

Yeah, understand you very well, I was looking for some accessories at Yarkoweb and after a few minutes of searching made a choice.

Has anyone had any problems with the Spool hpfp? My shop chose to use that over XDI and has been having problems with the pump not delivering sufficient fuel at idle. Spool is sending a replacement but my confidence is not high right now in Spool (or the shop).

Are you running a custom or OTS tune?

Custom tune. It seems to be a mechanical failure of the pump itself.

Dec540 had a similar issue with a Dorch but it was bc of the custom tune and OTS worked fine.

Have you tried an OTS map to see if the issue is still there? Who’s your tuner?

[Dec540]

I did have a similar issue. Effectively the pump was turning off at idle so the fuel pressure was dropping to low 100psi instead of around 1,200-1,300 (from memory - haven't looked at logs in months).

As ZM2 said, the issue wasn't present when running the OTS E30 mix tune with the correct HPFP selected in BM3. Come to think of it, just changing the HPFP settings to the Dorch pump on the custom tune also fixed it.

The tuner eventually fixed up the error in their tables that was causing the issue. The pump has been perfect ever since.

Definitely try the settings change before you commit to another 3+ hours of labour and increased likelihood of creating a boost leak.

The tuner said he bought a bootmod license, set it up and selected the Spool pump option but it still didn't work. The tuner is Cedar Performance in Dallas. They have a great reputation so I am sure he'll figure it out but it doesn't give me the warm fuzzies over the pump...
