Explain why not..........

[Notagain]

Soooo I love this 2018 A10 because of the transmission but the gen3 still seems to be limited with blower options.

Would it be insane to get rid of the DI heads and put GT350 heads on the higher compression gen3 short block? Few reasons for this.

1. more blower options like the wicked vmp gen3r or a big kenne bell.
2. more cam options with out the DI system.
3. more room in the valley for intercooler like the gen2s have.
4. 5.2 heads flow at least the same as the 2018 gen3 heads prolly more.

I dont see any downsides to going back to port only injection and as an added bonus the cars already got the 10 speed and higher compression.

Car would be on an E85 only diet anyways the added compression of the gen3 doesnt worry me. That and the moment this car gets boost itll no longer be a year round driver. Itll be demoted to toy.

Thoughts brainiacs cmon any reason this doesnt make sense? Is the DI really worth keeping on these considering Ill be feeding it E85 anyways?

Lets just call it a poor mans Predator.

12:1 compression 5.0 short block 5.2 heads port only injection 2650 blower.

Sounds kick ass to me. Especially with an A10 behind it.

It’s a really good question.

One side of my brain says: You’d have to pull some boost or timing out of it given the 12:1 CR without the DI to help settle things down.

Other side says: fuck that shit, e85 will make it virtually knock-proof (at least within the context of not chasing every single last Hp) and just go full send.

DI definitely does help reduce detonation, and improves power delivery. Agreed with Burkey that with even higher static compression some timing/boost will have to be sacrificed even on corn juice, or reduce cylinder pressure with cam timing. The only reason late model compression keeps climbing is controlling the actual cylinder pressure with cam profiles, direct injection, and cam timing actively changing. Detonation, and pushing head gaskets would be the result otherwise at higher static compression ratios with boost piled on.

My opinion you'd be taking a step backwards by removing the DI. Head flow 18 di - gt350 is negligible if any, cam options also negligible as they're proven to be very little benefit thanks to the massive flow from 4v heads, blower selection maybe slightly better but there is already badass DI blowers available, and more on the horizon for sure.

Without the DI, your PCM is gonna wonder WTF is going on, your dash is gonna light up like a Christmas tree and you’re in for a nightmare in tuning issues.

 

[Rjames18]

The real question is why? Especially when whipple and EB have been in the 8's. DI is wonderful on what it does.
I'm also pretty sure the water jackets won't line up

How do you figure? Im about 90% sure the fuel tuning lart would not be an issue as people upgrade the port injectors on the gen3s when going FI and basically zero people do anything with the DI side.

I also am pretty sure the 5.2 heads would work on a gen3 shortblock. Id have more questions about the cam gears amd timing chain setup more so than the heads physically fitting the block.

I dunno figured thia all would fit in theory but yes you can go 8s on a whipple or edlebrock kit for a gen3 anyways too.

 

[Vegas5OH]

The valley on the block is physically different, even if you swapped gen2 heads on there a gen 2 tvs lower manifold wont fit still i dont think.

There’s a DI pressure sensor that would problem #1. And I still believe that would just be one of many. Maybe you know something I don’t. Give it a try

 

[SoCalTim]

the gen3 still seems to be limited with blower options.

Huh? Whipple, VortechPaxton, Procharger, Edelbrock, Roush, Hellion etc all have 2018+ kits.

All the big players have kits out, not sure how options could be viewed as limited.

 

[olaosunt]

Hey OP
Still considering it ?

 

[gimmie11s]

VMP is supposed to have a nice 18+ kit out soon if they don’t have it out already.

Hey OP
Still considering it ?

Trying to close out details on a DOD job thatll be a game changer at the moment. As long as everything works out right big changes will be coming and ALOT more budget to play!!

 

[beefcake]

so many good blower options already seems like a lot of work, comp just released cams too
