My goal has been to run 8.90s. However my current build can't do that unless the DA is below 1000 ft. Chances of being able to race at that altitude are very slim. Therefore, I'm asking which modifications can I make from where I am right now to get there. I'll need at least 100 hp.

My build is pretty straightforward. A 390 with a ported 2650 on 100 octane and FBO.

Port injection, Whipple 3.0, change to Eth, N2O with fuel system, meth, or ?

More HP equals more air. I think your Eddie is out of steam and don’t think you can get another 10 lb/min airflow out of it. Nitrous is HP at any altitude lol.

Or, find a way to get some weight out if the car (not my preference either!).

What about a Whipple 3.0

[ramairroughneck]

You need a fuel system that supports full E85 and methanol.More oxygen is more power. I don’t see the Whipple 3.0 helping you on unleaded.

[ramairroughneck]

Also you are mentioning the ET that you are looking for not the mile per hour. I believe the suspension plays a crucial role there. Maybe the converter as well. Maybe I’m wrong but I believe there are a few more things to look at beyond the blower

[ZL14ever]

I suggest you work on your 60' first before thinking about adding more power. My C7 did 8.9 with only ~950 rwhp at +700 DA running ms109. My 60' was 1.29 & launch timing was pretty aggressive

I think nitrous is going to be the easiest way.

I suspect that could do it. I’m making about the same power as you with no blower porting and a conservative blower speed. There’s a lot more left in my 3.0.

JSH runs race gas… fueling isn’t the issue.

PD blower cars don’t need converter to 60’

Agreed, definitely room for improvement there.

From Denver, I have to drive three hours to get to a track at 3500 ft. and six hours to a 2200 ft. track. It's almost impossible to catch a 700 DA, where this build would run 9.00s.

A C7 is 300+ lbs. lighter than mine, which ran a 1.35 60 ft. last time out at 3500 ft. I don't see room for a lot of improvement as it sits today.

Ethanol by itself is usually worth power than a gasoline fuel on the same timing. Injecting fuel via port is usually less efficient on these engines than direct and you are taking up space in the intake runner that used to only be air. I think it could potentially get you that 100 horse you’re looking for just comparing and contrasting for arguments sake.

If you have the head room in your fuel system nitrous might be the easiest way to get there in your current configuration though.

I hope you have an auto trans. 1k+hp, drag slicks, change out the coilovers to something much softer to get the weight to transfer to the rear during launch.

A T400 with a trans-brake would lower the 60 ft. and ET, but would not be enough by itself.

To do nitrous, I'll need this to control the nitrous system, it's for a Holley EFI stand alone Fuel injection system kit
https://www.holley.com/products/fuel...parts/VK080000

I'll still need a bottle heater and standalone fuel system because my existing fuel system is already maxed out.

My shop has priced this N2O system at $11-12K.

I don't believe my current tuner has tuned such a build.

I've added info to my sig to help the conversation.

[nighttowl]

LME 390, E2650, FBO, 100 oct.
1116/967.
1.35/9.25/151 at 3500 ft.
15" conversion/MT ET Street R 325/50R15.

Very helpful, you're actually almost there.
Have you considered removing any weight?

Oof…that seems like a lot of $$$ for an extra 100 HP…
