E-Force blowers get hot. And they will cause the engine to pull timing and thus lose power. A friend of mine experienced that first hand. Plus he lost a good 3-4 tenths going from cool weather to hot Summer weather. So I can see how an E-force would need 15 PSI to make that kind of power. Turbos are much more efficient as they have no parasitic drag. So you'll make much more power at the same or lower psi as compared to a blower. But just curious, are you comparing the 2650 to the stock 1.7 or the 2650 to the Whipple in your comments?

Your going off LS3 info not LT1 info I have data logged mine hot and cold it pulls no more timing than my Zl1 on my old LS3 of course.

and your wrong... less PSI with more flow is why.. It simply moves more air at a lower psi period.. it doesn't take boost or psi to make powe when your moving more amounts and you will have less heat from lower psi.


I have seen the Test corvette for Eforce with an LT4 it picked up 100 plus to the tires with just a blower swap and its the old 2.3 style.

Like EDFHOBBIES said, the new E-force design/setup for the LT1/LT4 engines runs extremely well without any timing pull, even on a hot day. At first glance, it may seem that it runs hotter thane other PDs, but it's all in the IAT sensor location. See below.

I've also seen where the TVS 1700 on an LT4 Corvette pick up an extra 100 hp with an E-force TVS 2300 swapped in

Yes, exactly Ed unfortunately the LS3 history will haunt it forever..

No, I was going off of LT1 info. My friend has a 16 SS with E-Force on it. He made good power and ran very good times in cooler weather. But once it got warm out he lost 3-4 tenths in the quarter mile. After doing a smaller pulley and headers he dynoed less than before because the temps shot up. And I saw others at the track who were having similar issues once it got warmer out. The SS does not have the cooling design that the ZL1 has so that may be partially to blame. However now that it is cooler out he is making good power again. The TVS 2300s are good blowers but they do get hot on the SS.

There is no way he changed pulleys with out fuel mods. Not enough info here.. I haven't seen anything unusual on mine and im in houston 100degrees plus and 90 percent humidity the worst conditions.

I didn't say it was the stock fuel system. And I'm not posting his entire build. He was getting plenty of fuel. The problem was the temps. It was on a rather hot and humid day and he lost timing (resulting in a hp loss) while on the dyno. Also he was running 3-4 tenths faster in the quarter mile on cool days than he was when it got hot outside. I went with him to the track several times. He has an upgraded fuel pump and of course upgraded injectors. Now maybe you have different experiences or a different setup or a tuner who does things differently or maybe your temps and humidity when your car was tuned was better than what we get here in NJ. Who knows. There are lots of variables that affect different setups. I'm just stating what I know. I'm not challenging you and I don't care to be challenged either. If your experiences are different then that is noted. But I've seen differently. For the record, the guys with centri blowers were running consistent times (according to them) in the hot weather as they were when it was cool out.
