Hey guys, I just ordered a whipple kit for my pp1 auto 18 gt and I have a few questions.

Current power mods are just a 3" mbrp catback and e85 tune from pbd. Current suspension mods are just steeda ultralight jacking rails and rear subframe brace. Brakes are also 2 piece baer rotors.


I ordered the kit with current list of items :

Whipple gen 5 SC
Whipple oversized heat exchanger
ID 1050x injectors
JMS BAP
132mm Throttle body
NGK 6510 spark plugs
VMP IAT relocation harness
Reische 170* thermostat
3.625 pulley

Will I need a fuel pump or is the stock pump + the JMS booster good enough for 93 octane with the 3.625 pulley? I would like to have ~725 rwhp and I plan on staying on 93 octane for at least a year or maybe indefinitely. In the future I may eventually get a fuel system for e85 and also probably add more clutches to the transmission if/when I do go e85. Let me know if you guys have any suggestions or if I am missing anything. Thanks.

I’m getting ready to do an install on my 350. Two I’m doing for sure is the rear heads cooling mod(cross over tube) and driveshaft. I’m doing a clutch as well but that doesn’t apply to your application.

edit: opg’s as well.

I am assuming you got a tuner kit? Whipple for their stage two kits uses a DW 400 fuel pump. I am pretty sure with a BAP you will still be alright, however, I don't think the 3.625 is a good pulley for pump gas unless you're adding Boostane 3.75 or 3.875 are safer and can get you to your power goals. no point in adding boost if you're pulling timing to stop knock. Last thing is, if you can catless headers are almost a must on a boosted car I damaged my cats within a week of install on a really long highway pull.

That pulley is a little To small IMO. With a bap the fuel pump should be enough but 93 I’m not sure about that

I'd update to a full return fuel system - Yeah, another $2K - Remember that phrase...Just "another $2K".

Seriously, running lean is bad juju.

I just installed mine last weekend. Stuff I didn’t account for; coolant (at least 3 gallons), oil, tools (specialty ones). I did OPG/CS at the same time so my list of necessary tools may be different.

I do want to keep my cats, im hoping they are fine at this power level. Ill keep that in mind though. Ill see what the tuner says about pulley ive seen a few 93 cars on youtube running 3.625 with no apparent problems making about the power I want. I may go with a griptec pulley. The kit does come with a 3.875 pulley but I wanted more than base boost. Its a beefcake special kit.

I have been thinking about doing a fuel system but I havent been able to talk to my tuner yet, I think they are off until 2021. I want to see what my tuner and shop think of the jackal JR fuel system. The thing is, if I did a return style I would go e85, and then I would probably be making 850 rwhp and at that point I think stuff like the transmission would start failing and possibly the motor and catalytic converters. I dont want to also build the transmission yet, although I am somewhat considering it. Also I wasnt planning on building the motor or doing OPG's. I will consider atleast doing OPG's though, ill ask my tuner when they get back.

Is e85 always safer than 93 for the motor? For example is it safer to make like 800 rwhp with e85 instead of 725 rwhp on 93 octane? I may go with a fuel system if its just safer overall for the motor. I guess I could go with less boost and still shoot for 725-750 rwhp on e85 but make it super safe for the motor. I wonder what pulley I would need to make 725-750 rwhp on e85. I really dont want to have any motor problems, just watched a few youtube videos of ppl with whipples having some motor problems and most if not all were on pump gas not e85. Some rod knock, some cracked piston ring lands etc.

Also I wonder why whipple recommends such heavy oil to be put in, 5w50 seems pretty heavy and this motor was designed for 5w20, doesnt seem like a good idea to go that heavy on oil weight, and I have a lot of 5w30 sitting here in my house that I bought for future oil changes already.

You will make 725+ on just the stage 2 kit alone at the wheels with 93 octane (I would say 750-760ish). As for oil, I run Rotella T6 5w40 synthetic since installing my stage 2 on my 19. Mine went 10.23 @138 with a 2.2 60'. That sixty killed me. I was thinking fuel system too but I am more than happy with the power it makes for now and dont wanna have to beef the trans up anytime soon.

Boost a pump may not always work. Go for DW400 now included with a built in check valve. Solid choice on the injectors they are the best.

Stage 2 kit comes with DW400, 37lb injectors, denso spark plugs n all. Totally complete. Or atleast mine came with all that.

How much power did you end up adding? Are your cats holding up or did you remove them ?

Not sure number wise but quite a bit. My cats are gone, installed stainless power LTH with no cats. Mods are in my signature
