2023年6月6日 · C7 Z06 Discussion - Before and After Dyno Results after Ported LT4 Supercharger - We are very excited to be seeing amazing results with our latest CNC Ported LT4 superchargers on customer cars across the country. This test was done by Complete Street Performance in West Chester, PA. BEFORE: Bone stock 2017 ZL1 AFTER:...

2014年8月8日 · C4 Tech/Performance - Dyno #'s LT4 w Hot Cam - Finally got my mainly stock LT4 dyno tuned today. I had to rebuild it after spinning bearings late last year. Specs are stock LT4 except an LT4 Hot Cam from GMPP, Stainless Works Headers and Corsa Exhaust.

2011年3月6日 · C4 Tech/Performance - 96 LT-4 Dyno Results - Well, I got the 96 Dyno'd last Thursday and was quite pleased. My goal after a few bolt on mods and a dyno tune was to have 300 at the rear wheels. I wanted to do a dyno run before my mods and thats exactly what I did. Needless to say, I was quite happy at the numbers. SAE...

2014年10月2日 · According to the dyno chart, the LT4 produces 457 lb-ft of torque just off idle and 625 lb-ft by 2,800 rpm. By comparison, according to GM’s numbers, a V12 engine from a Ferrari Berlinetta offers 28 percent less torque even though it produces 12 percent more top horsepower.

DynoJet testing of ZZ4-TPI w/ LT4 HOT cam To compare the benefit (anticipated) of the AFR190 heads, I took my car up to a local shop with a DynoJet Chassis Dyno for some "pre-swap" tests. The graphs and data are below:

2006年12月1日 · On Kenny Duttweiler's dyno it made right around 300 hp, normally aspirated, which was cool considering the very small cam. Jeff kept the camshaft small to have lots of cylinder pressure at low...

2014年5月19日 · Its never bin on a dyno, only mail order tune. As far as elevation and weather, nothing really changes I drive I the same area and its only driven in the summer months. I might just have to pay and get it tuned on a dyno,

2003年2月3日 · Just had a recent Dyno day in Virginia and the GS with just a K&N filter and Corsa exhaust Dyno'd in at 304 HP and 310 torque. We had two other LT4's up there that day one completely stock that dyno'd at 293 hp and another with a flowmaster exhaust and a cold air induction which had 305 HP.

2002年5月21日 · My LT4 recently posted runs on a Dyno at about 300HP. Does anyone know what the factory HP specification was on this model at the back wheels or have comparable data for a stock LT4? Good numbers, the GM number was 330 crank, but yours and others prove that its more like 350 crank.

We’ve learned the LT1/LT4 engines absolutely benefit from additional displacement, and stroker cranks are popular upgrades around here. These dyno sheets represent twenty years of testing the LT1, including many equipped with the Mini Ram intake manifold we developed in-house.
